Question

Rani ate 2/7 part of cake while her brother Ravi 4/8 of remaining what part of the cake is left​

Answer 1

Answer:

1/7

Step-by-step explanation:

Rani ate 2/7 part of a cake while her brother Ravi ate 4/5 of the remaining. Part of the cake left is 1/7. Now, let us assume total part of cake be 1. Then, from the questions, given that Rani ate 2/7 part of a cake = 1 – (2/7) = (7 – 2)/7 = 5/7 So, Ravi ate 4/5 of the remaining cake = (4/5) × (5/7) = 4/7 Therefore, the part of the cake left = (5/7) – (4/7) = 1/7

Answer 2

Step-by-step explanation:

let the total part is 1

1-2/7=5/7

5/7-4/8=11/28 part is left
