As well as continuing our general revision, we looked at fractions of numbers. To find a half of a number, divide by 2. To find a third of a number, divide by 3. If the top number is not 1, multiply your answer by the top number. Two thirds of 27 is 9 x 2 = 18.
We did a harder question about a barrel of apples. The key is to notice that one third of the apples must be good. We are told that 24 apples are good, so 24 must be one third of the total. To get the total we multiply 24 by 3.
