Tessa cooked cassava cake and shared among her three friends. Melba got 4/7 of it and Sonia got 2/5 less than Melba. What fraction of the cassava caked did Anya get?​

Answer:

I suppose Tessa is not going to eat the cassava cake.

So, Melba got 4/7 of the cake

Sonia got 4/7 - 2/5 = x

Anya got 1 - (4/7 + x)

Let us first find the value of x.

4/7 - 2/5 = (20-14)/35 = 6/35

Sonia got x=6/35 of the cake. That's way too little. How unfair.

Let us now calculate Anya's share.

1 - (4/7 + 6/35)

1 - (20+6)/35

1 - 26/35

35/35 - 26/35

9/35

Anya got 9/35 of the cake. Still too little. -_-
