Answer 2

Given:

• A cake which is cut into 5 equal parts.
• Shabnam eats one part or $\dfrac{1}{5}$ of it.
• She gave her sister two parts or $\dfrac{2}{5}$ of it.

What to find?

We have to find how many parts of cake is left out.

How to find?

To find how much is left we will add $\dfrac{1}{5}$ and $\dfrac{2}{5}$ and then subtract $\dfrac{5}{5}$ from it.

Solution:

First add $\dfrac{1}{5}$ and $\dfrac{2}{5}$,

⇒ $\dfrac{1}{5}+\dfrac{2}{5}=\dfrac{3}{5}$

Now subtract $\dfrac{3}{5}$ from $\dfrac{5}{5}$,

⇒ $\dfrac{5}{5}-\dfrac{3}{5}=\dfrac{2}{5}$

∴ So, $\dfrac{2}{5}$ of the cake is left with Shabnam.
