Answer:

3/4 = 9/12

5/3 = 20/12

Explanation:

You can find the numerator of the fraction by multiplying the fraction by 12. Equivalently, find the factor the denominator must be multiplied by to make 12. Multiply the numerator by that same factor.

3/4 = (3/4)(3/3) = (3∙3)/(4∙3) = 9/12

5/3 = (5/3)(4/4) = (5∙4)/(3∙4) = 20/12
