This is how I work out 4x35=140 (4x30=120) + (4x5=20)
This is how I work out 3x39 (3x40=120) -3 =117

51 divide a by 3
well first i split 51 into 30 because ten 3's go into thirty, that leaves 21, so I can get 7 3's from 21, that means from 51 I can get 17 3's.

today i am solving 57 divided by 3 first i split them into two groups 30 and 27 - then I work out how many threes are in each of these and join them together.
I would need a calculator to do this...you are very clever...keep up the great work on your maths. Love Mum
