Given,

Part of Apple eaten by Ritu =    \frac{3}{5}  .

Part of Apple eaten by Somu:

\Rightarrow 1-\frac{3}{5}

\Rightarrow \frac{1}{1}-\frac{3}{5}

LCM of 1 and 5 is 5. So making the denominator of both fraction equal to 5, we get 

\Rightarrow \frac{1}{1}\times\frac{5}{5}-\frac{3}{5}

\Rightarrow \frac{5}{5}-\frac{3}{5}

\Rightarrow \frac{5-3}{5}

\Rightarrow \frac{2}{5}

Hence, The Part of Apple eaten by Somu is 2/5.

Now, As 

\frac{3}{5}> \frac{2}{5}

\frac{3}{5}- \frac{2}{5}=\frac{3-2}{5}=\frac{1}{5}

Hence, Ritu had a larger share of the apple by \frac{1}{5} part.
