Answer:

84

Explanation:

4 : 12 = 28 : x

If you do something to one side you have to do the same thing to the other side.

28 ÷ 4 = 7

12 × 7 = 84

Hope This Helps :)

Answer:

84

Explanation:

We can set up a proportion using fractions.


(4)/(12) = (28)/(x)

Now, let's cross multiply by multiplying 12 and 28 then dividing by 4.


12\cdot28=336\\\\336/4=84

Hope this helped!
