Question

13. Tonia and Trinny are twins. Their friends give them identical cakes for their birthday. Tonia eats ⅛ of her cake and Trinny eats ⅙ of her cake. How much cake is left? ​

Answer 1

If Tonia eats 1/8 of the cake, then the fraction of the cake left is:

1 - 1/8 = 7/8

If Trinny eats 1/6 of the cake, then the fraction of the cake left is:

1 - 1/6 = 5/6

Since Tonia and Trinny have identical cakes, the amount of cake left is the same for both of them. Therefore, the amount of cake left is:

(7/8 + 5/6) / 2 = 41/48

So there is 41/48 of the cake left.
