Question

What number fits in the box to complete the equation?

Answer 1

we have the equation

`8(1)/(2)\colon(1)/(x)=51`

step 1

Convert mixed number to an improper fraction

so

8 1/2=8+1/2=17/2

substitute

`\begin{gathered} (17)/(2)\colon(1)/(x)=51 \\ \text{Multiply in cvross left side} \\ (17x)/(2)=51 \end{gathered}`

Multiply by 2 both sides

17x=102

Divide by 17 both sides

x=102/17

1x=02/17=6

therefore

the answer is 6
