## Question

Ritu ate \begin{align}\frac{3}{5}\end{align} part of an apple and the remaining part was eaten by his brother Somu. How much part of the apple Somu eat? Who has the larger share? By how much

## Text Solution

What is Known?

Parts (fraction) of the apple which Ritu ate.

What is unknown?

Who ate the larger part of the apple and by how much.

Reasoning:

Compare the fractions and decide which one is larger.

Steps:

Part (fraction) of apple eaten by Ritu $$=$$ \begin{align}\frac{3}{5}\end{align}

Part of apple eaten by Somu $$=$$ $$1$$- Part of apple eaten by Ritu

\begin{align} = 1 - \frac{3}{5}\end{align} = \begin{align}\frac{2}{5}\end{align}

Since\begin{align}\frac{3}{5}\end{align} > \begin{align}\frac{2}{5}\end{align} , Ritu ate larger share.

Difference between their shares $$=$$ \begin{align}\frac{3}{5} - \frac{2}{5} = \frac{1}{5}\end{align}

Thus, Ritu’ s part is \begin{align}\frac{1}{5}\end{align} more than Somu’s part.
