Question

Mother baked a cake and gave 1/6 of the cake to the son and 1/5 of the cake to her daughter how much of the cake is left.

Answer 1

Hey guys
We can take the LCM of 5 and 6 that is 30

1/5*6/6=6/30
1/6*5/5=5/30

We can add them that is equal to 11/30

Therefore the amount of cake left is equal to
19/30 (30/30-11/30)


Hope it helps..

Answer 2

The part of the cake given=1/5+1/6=11/30

Part of cake left=30/30-11/30=19/30
