3/7 = 9/x
cross multiply because thats how u solve proportions
(3)(x) = (7)(9)
3x = 63
x = 63/3
x = 21
and if u will notice : 3/7 and 9/21 ....9/21 reduces to 3/7....so these are equivalent fractions...because proportions are nothing but equivalent fractions
Well you need to explain what is going on here so try to rephrase this.
Answer
The answer is most likely 2 (or C).
Why?
The top of the question simplified into number is 2(5 + 3), which equals 16.
The bottom is (3 +5)1, which equals 8.
Now divide 16/8, which equals 2, and there's your answer.
