    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

    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
