Chapter 6, Problem 13MCQ

To determine

To tell :whether the ratio from a proportion for $\frac{8}{18},\frac{12}{27}$ .

Answer to Problem 13MCQ

The ratio $\frac{8}{18},\frac{12}{27}$ isin a form of proportion.

Explanation of Solution

Given information : consider, the proportionprovided in the question,

  $\frac{8}{18},\frac{12}{27}$ .

Formula used :cross product property −

  $\begin{array}{l}\frac{a}{b}=\frac{c}{d}\\ ab=cb\\ \end{array}$

Calculation : to solve this use cross product property,if the ratios verify the cross product property then it will form the proportion.

Consider the ratios form proportion so use cross product property,

  $\frac{8}{18},\frac{12}{27}$

  $\begin{array}{l}\frac{8}{18}=\frac{12}{27}\\ 8·27=12·18\\ 216=216\end{array}$

Hence,

Thus,The ratio $\frac{8}{18},\frac{12}{27}$ is in a form of proportion.
