Question

Write an equivalent fraction with a denominator of 100.

3/4= ?/100

Answer 1

Answer: 3/4 = 75/100

Step-by-step explanation:

3/4 = x/100

(X = unknown number)

You can do cross products by taking the denominator and multiplying by the opposite numerator and doing the same for the numbers left out.

For example: You would do 4 times X and 3 times 100 which equals 4x = 300

Then you isolate the variable (x) by dividing 4 by 4 (which is zero) and then dividing 300 by 4 as well (which is 75)

Then it would be x = 75

To check you can simplify 75/100

Answer 2

75/100

There's two ways to answer this question, I'll start with the easier way first.

You know that 4 times 25 is 100, and that means in order to make the denominator 100, you have to multiply the numerator by 25 too.
So:
3/4 * 25/25 = 75/100

You could also cross multiply:
3/4 = n/100
3*100 = 4 * n
4n = 300
n = 75
