Answer to Problem 51E

  $x=5$

Explanation of Solution

Given information: $\frac{x}{12},\frac{80}{192}$

Formula Used: Factorisation

Calculation:

To make fraction equivalent, cross multiply of $\frac{x}{12}=\frac{80}{192}$

  $x\times 192=80\times 12$

This gives us-

  $192x=960$

Dividing both sides by 192

  $x=\frac{960}{192}$

Hence x is-

  $x=5$
