Step 1: Understand Place Value

The number 0.175 has three digits after the decimal point:

1 is in the tenths place (1/10)

7 is in the hundredths place (7/100)

5 is in the thousandths place (5/1000)

So, we can write it as:

But there’s an easier way!

Step 2: Write It as a Fraction Over 1000

Since the last digit (5) is in the thousandths place, we can write:

Step 3: Simplify the Fraction

Now, let’s make 175/1000 as simple as possible. We do this by finding the Greatest Common Divisor (GCD) of 175 and 1000.

Factors of 175: 1, 5, 7, 25, 35, 175

Factors of 1000: 1, 2, 4, 5, 8,10, 20, 25, 40, 50, 100, 125, 200, 250, 500, 1000

The biggest number that divides both is 25.

Now, divide numerator and denominator by 25.

Final Answer:

what is equal to 0.175

0.175 is equal to the fraction 7/40

Decimal to Fraction Chart

Step 1: Understand What 0.25 Means

The number 0.25 is called a decimal. It means you have 25 hundredths- or in other words, 25 out of 100.

Why?

Because:

The first number after the decimal point is tenths.

The second number after the decimal point is hundredths.

So, 0.25 = 25 hundredths = 25/100.

Step 2: Write It as a Fraction

We now know:

0.25 = 25/100

That’s your fraction form, but we can make it even simpler!

Step 3: Simplify the Fraction

Fractions can often be simplified by dividing both the top number (numerator) and the bottom number (denominator) by the same number.

Let’s simplify 25/100:

Both 25 and 100 can be divided by 25.

So:

25 ÷ 25 = 1

100 ÷ 25 = 4

Final Answer: 0.25 = 1/4

what is equal to 0.25

0.25 is equal to the fraction 1/4 or 25%.

What Are the Factors of 75?

To find all the factors of 75, start from 1 and go up to 75.

Try dividing 75 by each number. If it divides evenly (no remainder), then that number is a factor.

Try 1: 75 ÷ 1 = 75 so, 1 is a factor.

Try 2: 75 ÷ 2 = 37.5 Not a whole number. So, 2 is not a factor.

Try 3: 75 ÷ 3 = 25 Yes! 3 is a factor.

Try 4: 75 ÷ 4 = 18.75 Not a factor.

Try 5: 75 ÷ 5 = 15 Yes! 5 is a factor.

Factors of 75 = 1, 3, 5, 15, 25, 75

Find Factor Pairs of 75

Positive Pair Factors of 75

Let’s look at all the positive numbers that can be multiplied together to give 75.

1 × 75 = 75 → So, (1, 75) is a pair factor

3 × 25 = 75 → So, (3, 25) is a pair factor

5 × 15 = 75 → So, (5, 15) is a pair factor

Positive Pair Factors of 75 = (1, 75), (3, 25), (5, 15)

Negative Pair Factors of 75

Now let’s talk about negative pair factors.

When you multiply two negative numbers, you also get a positive number!

So we can create pairs like this:

–1 × –75 = 75 → So, (–1, –75) is a pair factor

–3 × –25 = 75 → So, (–3, –25) is a pair factor

–5 × –15 = 75 → So, (–5, –15) is a pair factor

Negative Pair Factors of 75 = (–1, –75), (–3, –25), (–5, –15)

Prime Factorization of 75

Another way to find factors is by breaking 75 into its prime factors:

Divide 75 by the smallest prime number (3):

75 ÷ 3 = 25, 3 is a prime factor.

Now, factorize 25:

25 ÷ 5 = 5, 5 is a prime factor.

Finally, factorize 5:

5 ÷ 5 = 1, 5 is again a prime factor.

So, the prime factorization of 75 is:
75 = 3 × 5 × 5 or 3 × 5²

What Are the Factors of 74?

To find the factors of 74, we divide it by integers starting from 1 up to 74 and check which numbers leave no remainder.

1 × 74 = 74
2 × 37 = 74

Thus, the factors of 74 are: 1, 2, 37, 74.

Pair Factors of 74

Pair factors are the pairs of numbers that multiply to give 74. Let’s find them:

1 × 74 = 74
2 × 37 = 74

Pair Factors: (1, 74) and (2, 37)

For negative pair factors:

(-1, -74) and (-2, -37) also work because the product of two negative numbers is positive.

Prime Factorization of 74

Prime factorization involves breaking the number down into its prime factors:

Start with the smallest prime number, 2.
74 ÷ 2 = 37 (since 74 is even, it’s divisible by 2).

Next, check if 37 is prime. It is, as it’s not divisible by any number other than 1 and 37.

Prime Factorization of 74: 2 × 37

Factor Tree of 74

The factor tree represents the prime factorization visually. For 74:

Start with 74 at the top.
Split 74 into 2 × 37.
Both 2 and 37 are prime numbers, so the tree ends there.

Factors Calculator

Step 1: Start with 1 and 74

1 and 74 are factors of 74 because 74÷1=74 and 74 ÷ 74 = 1.

Step 2: Check for divisibility with smaller numbers

Start testing smaller numbers to see if they divide 74 completely.

• 2: 74÷2=37, so 2 and 37 are factors.
• 3: 74÷3=24.67 (not a whole number, so 3 is not a factor).
• 4: 74÷4=18.5 (not a whole number, so 4 is not a factor).
• 5: 74÷5=14.8 (not a whole number, so 5 is not a factor).
• Continue checking up to √74≈8.6.

Step 3: List all factors

The factors of 74 are: 1, 2, 37,and 74.

• Positive factors of 74: 1, 2, 37,and 74
• Negative factors of 74: -1, -2, -37,and -74

Key Notes:

• 74 is not a perfect square, so it doesn’t have repeated factors.
• 74 is a composite number (not prime) because it has factors other than 1 and itself.

For example:

19 × 1 = 19
19 × 2 = 38
19 × 3 = 57
19 × 4 = 76
19 × 5 = 95

The first few multiples of 19 are easy to identify. They start from 19 and continue by adding 19 repeatedly. Here’s how the sequence looks for the first few numbers:

First Five Multiples of 19:

19
38
57
76
95

As you can see, every time you multiply 19 by a natural number, you get a number that is evenly divisible by 19. In other words, when you divide these multiples by 19, you get a whole number with no remainder.

The First 10 Multiples of 19:
To find the next set of multiples, simply continue multiplying 19 by the next set of whole numbers.

19 × 6 = 114
19 × 7 = 133
19 × 8 = 152
19 × 9 = 171
19 × 10 = 190

So, the first 10 multiples of 19 are:
19, 38, 57, 76, 95, 114, 133, 152, 171, 190

The First 20 Multiples of 19:
If we continue this pattern for the next set of numbers, we get:

19 × 11 = 209
19 × 12 = 228
19 × 13 = 247
19 × 14 = 266
19 × 15 = 285
19 × 16 = 304
19 × 17 = 323
19 × 18 = 342
19 × 19 = 361
19 × 20 = 380

So, the first 20 multiples of 19 are:
19, 38, 57, 76, 95, 114, 133, 152, 171, 190, 209, 228, 247, 266, 285, 304, 323, 342, 361, 380

Fun Fact: Prime Nature of 19

19 is a prime number, meaning it has only two factors: 1 and itself. This makes its multiples especially unique. Every multiple of 19 is either 19 itself or a product of 19 with a natural number. For example, 38 is just 19 × 2, 57 is 19 × 3, and so on.

Why is 79 a Prime Number?

A prime number is defined as any number greater than 1 that has only two factors: 1 and itself. Let’s test the divisibility of 79 to confirm this:

79 ÷ 1 = 79

No remainder is left, so 1 is a factor.

79 ÷ 79 = 1

Again, no remainder is left, so 79 is also a factor.

Next, we check divisibility by other numbers:

79 ÷ 2 = 39.5 (Not divisible)
79 ÷ 3 = 26.33 (Not divisible)
79 ÷ 4 = 19.75 (Not divisible)

Continuing this process, we find that no other numbers divide 79 evenly. Thus, 79 is confirmed as a prime number.

Pair Factors of 79

Factors can also be expressed as pairs of numbers that multiply to give the original number. For 79, the pair factors are:

Positive pair: (1, 79)
Negative pair: (-1, -79)

This means the product of these pairs always equals 79:

1 × 79 = 79
-1 × -79 = 79

Prime Factorization of 79

Prime factorization involves breaking a number down into its prime components. Since 79 is already a prime number, it cannot be broken down further. Its prime factorization is simply:
79

In exponential form, this can be written as:
