1/6 Book

GalinKa [24]

Given:

$\frac{1}{6} \text{ book in } \frac{2}{3} \text{ hours}$

To find:

Number of books per hour

Solution:

We have to calculate the book read in one hour.

$\frac{1}{6}\text{ book }\rightarrow\frac{2}{3}\text{ hour}\\\\\text{we have to multiply both the side with 2/3}\\\\\frac{1}{6}\times\frac{3}{2}\text{ book }\rightarrow\frac{2}{3}\times\frac{3}{2}\text{ hour}\Rightarrow\frac{1}{4}\text{ book }\rightarrow1\text{ hour}$
