Chapter 6, Problem 11MCQ

To determine

To tell :whether the ratio form a proportion for $\frac{25}{36},\frac{5}{6}$ .

Answer to Problem 11MCQ

The ratio $\frac{25}{36},\frac{5}{6}$ is in a form of proportion.

Explanation of Solution

Given information : consider, the ratiosprovided in the question,

  $\frac{25}{36},\frac{5}{6}$ .

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 ratio verify the cross product property then, it will form proportion.

Consider the ratios form proportion, then use cross product property

  $\frac{25}{36},\frac{5}{6}$

  $\begin{array}{l}\frac{25}{36}=\frac{5}{6}\\ 25·6=5·36\\ 150=150\end{array}$

Hence,

Thus,The ratio $\frac{25}{36},\frac{5}{6}$ is in a form of proportion.
