Question

A bakery has 15whole3/5 kg of cake.If it sells 13 whole 1/4 kg of it, Find how much cake is left.​

Answer 1

Step-by-step explanation:

Given the equivocal nature of this question, I will need to draw an assumption: I will assume that Ali ate from the cake and so did Jason — not Ali ate from the cake and Jason ate from Ali’s slice.

With that being said, the first approach is make both of these fractions have a common denominator, so that we can find how much each respective person ate from the total amount of slices. Intuitively, the common denominator is 12 , so this must be true:

Ali ate 4/12 of the cake;

Jason ate 3/12 of the cake

Adding these two fractions will give us 7/12 — the total amount eaten. Now, to find the amount left, we need only subtract 7/12 from 12/12 (the total amount of the cake). Doing so will give us

12/12−7/12=5/12

Thus, 5/12 of the cake was left uneaten.
