4

Answer 5

ok so multiply 4 by 4 and what do you get?

Answer 6

16

Answer 7

that is the answer

we had \(\dfrac{3}{4}\) and we want to make that equal to \(\dfrac{12}{x}\)

Since we needed to multiply the top by \(4\) to get \(12\), that means we must multiply the bottom by \(4\) to get the answer.

Answer 8

in other words \(\dfrac{3}{4}=\dfrac{3}{4}\times 1=\dfrac{3}{4}\times \dfrac{4}{4}=\dfrac{12}{16}\)
