Answer 2

Answer:

The fourth part of the cake is 1/8.

Step-by-step explanation:

Given a cake is divided into 4 parts of which three parts are 1/2, 1/4 and 1/8.

To find the fourth part of the cake.

Consider complete cake = 1.

Let the fourth part of the cake be x.

Then, $\frac{1}{2} +\frac{1}{4}+\frac{1}{8} +x=1$

$\frac{4+2+1+8x}{8}=1$

      $\frac{7+8x}{8}=1$

   $7+8x=8$

          $x=\frac{1}{8}$

So, the fourth part of the cake is 1/8.
