Question

A birthday is divided into 12 equal parts. Andrew eats 3/12 of the cake and Timothy eats 1/12
What fraction of the cake is left?
How many pieces of cake are left
Could someone please explain to me the answer

Answer 1

OK let's start with 12/12 (since that is where you start) and subtract 12/12 from 3/12 (that's how much Andrew ate) so 12/12-3/12 which equals 9/12 and subtract 1/12 and you would get......


8/12 

Answer 2

the answer would be 8/12 because if you add up 3/12 and 1/12 you get four 12 s then you subtract 4/12 from 12/12 and walahh you get your answer
