8x24=192
192/8=24
5x29=145
145/5=29
We found this out by swapping the numbers around. You can either put 24 or 8 in the middle of a division. In divisions,if you put 8 in the middle the answer is 24 if you put 24 in the middle the answer is 8. In divisions the first number is always the biggest number. For multiplying the answer of the sum is always the start of the divisions. It is harder to do a division if you haven't got a multiplication for it.
You can turn a dividing sum into a multiplication sum by swapping the numbers around and you can turn a multiplying sum into a division sum.
These are some questions from our maths text book.
