Answer:
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 = 12/9....so is this
I could go on, but I think u get it....
another way this could be done is proportions....because they are nothing but equivalent fractions
4 / 3 = x / 21.....cross multiply and solve for x
(3)(x) = (4)(21)
3x = 84
x = 84/3
x = 28 <===
