Step-by-step explanation:

Step-by-step explanation:

 4          7          28

  x     =    <===

3            7          21

u can find equivalent fractions by multiplying the numerator and denominator by the same number

4/3 * 2/2 = 8/6...this would be equivalent

4/3 * 3/3 = 12/9so is this

I could go on, but I think u get it

another way this could be done is proportionsbecause they are nothing but equivalent fractions

4 / 3 = x / 21cross multiply and solve for x

(3)(x) = (4)(21)

3x = 84

x = 84/3

x = 28 <===
