Question

Mini ate of a whole cake. What is the fraction of the cake that is left to eat ?​

Answer 1

Answer:

depends on the question, the meaning of ‘it’:

if you have a whole cake, and ate 3/8 of this whole cake, answer is simple: 5/8

1 - 3/8 = 8/8 - 3/8 = 5/8

but:

if you have a whole cake, and you ate a part, and you see what you ate is 3/8 of the remaining part:

remaining part is x

you ate 3/8x

together it is whole cake

x + 3/8 x = 1

8/8 x + 3/8 x = 1

11 /8 x = 1

x = 8/11

Here is the answer: 8/11 of the cake is remaining.
