Question

Rani ate 2/7 part of a cake while her brother Ravi ate 4/7 of the remaining what part of the cake was left

Answer 1

Hey mate!!!!!

Rani ate 2/7
Ravi ate 4/7
They together ate =
$\frac{2}{7} + \frac{4}{7} = \frac{6}{7 }$
remaining piece =
$1 - \frac{6}{7} \\ = \frac{7}{7} - \frac{6}{7} \\ = \frac{1}{7}$
1/7 is remaining.


Hope it helps dear friend ☺️✌️✌️✌️

Answer 2

Hey mate !!

Here's the answer !!

We can consider the whole part of the cake to be 1 which is 7 / 7  pieces.

So it is given that, Rani ate 2 / 7.

=> Remaining pieces = 7 / 7 - 2 / 7 = 5 / 7

After that Ravi ate 4 / 7 pieces of the remaining cake.

=> Remaining pieces = 5 / 7 - 4 / 7 = 1 / 7

Hence the total number of pieces or parts of cake left was 1 / 7 of the whole cake.

Hope my answer helps !!

Cheers !!
