please explain step by step

Answer 1

Answer:

She has left 5/12 part of a cake.

Step-by-step explanation:

first we take a whole cake=1

then we subtract the whole cake with with of their friends.

=1×1/4×1/3

We take the lcm of 3 and 4 which is 12.

12-3-4/12=5/12

hence,5/12 is the correct answer.

Answer 2

Answer:

Part of cake Shipra left with 7/12

Step-by-step explanation:

Given:

Shipra gave 1/4 of the cake to one friend, and 1/3 another friend.

1/4 of whole cake is 1/4 × 1 ,1/3 of whole cake is 1/4 × 1.

So the part of cake Shipra left with.

1 - (1/4 × 1 + 1/3 × 1) = 1 - {(3+4)/12} = 1 - 7/12 = (12 - 5)/12 = 7/12
