Explanation:
12p = £0.12
to answer how many elastic bands are in the bag we need to find out how often £0.12 fits into £6.
and that we do by division :
6 ÷ 0.12 = 50
so, there are 50 elastic bands in the bag.
if you cannot use a calculator, this is how you solve this by hand relatively easily :
6 / 0.12 = 6 / 12/100 = 6 × 100/12 = 1 × 100/2 = 50
