Question

Solve the proportion below. X O A. 56 O B. 66 O C. 50 D. 60 PREVIOUS

Answer 1

we have

`\begin{gathered} (55)/(x)=(5)/(6) \\ \end{gathered}`

solve for x

`\begin{gathered} x*(55)/(x)=(5)/(6)* x \\ 55=(5)/(6)x \\ 55*(6)/(5)=(5)/(6)x*(6)/(5) \\ x=(330)/(5)=66 \end{gathered}`

answer: B. 66
