He gave 15 cakes to Helen.
He gave 20 cakes to Sue.
20 + 15 = 35
He gave away a total of 35 cakes.
60 - 35 = 25
He has 25 cakes left.
fraction = 25/60 = 5/12
To find the average, find the mean: add all the numbers together and divide by the number there is.
First add all the numbers together:
39 + 43 + 28 + 36 + 29 = 175
Next, divide 175 (the total) by 5 (because there are 5 numbers)
175/5 = 35
35 is your average.
