Answer:
84
Step-by-step explanation:
We can set up a proportion using fractions.
[tex]\frac{4}{12} = \frac{28}{x}[/tex]
Now, let's cross multiply by multiplying 12 and 28 then dividing by 4.
[tex]12\cdot28=336\\\\336\div4=84[/tex]
Hope this helped!
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 :)
