Rani ate 2/7 part of the cake while her brother Ravi ate 4/5 of the remaining. Part of the cake left is __________
Solution:
Let us assume the whole part of the cake is 1.
Part or fraction of the cake eaten by Rani = 2/7
Left part = 1 - 2/7 = 5/7
Part of the cake eaten by Ravi = 4/5 × 5/7 = 4/7
Therefore the part of a cake left = 5/7 - 4/7 = 1/7
Rani ate 2/7 part of the cake while her brother Ravi ate 4/5 of the remaining. Part of the cake left is 1/7
