Question

Hellppppwhat's the missing number? 7/16 = ?/64a) 4b) 21c) 28d) 55

Answer 1

Let x represent the missing number, and you'll now have;

`\begin{gathered} (7)/(16)=(x)/(64) \\ \text{Cross multiply and you have;} \\ 7*64=16x \\ \text{Divide both sides by 16} \\ (7*64)/(16)=(16x)/(16) \\ 7*4=x \\ 28=x \end{gathered}`

Therefore, the missing number is 28
