two steps

these resources explore how to get from one number to another by involving multiplications and divisions only (no addition or subtraction) in two steps

this is a prelude to work on 'boxes' for ratio questions

the powerpoint is here

for these tasks, the operations are limited to using multiplication and division by a digit

it can be interesting to relate different ways of doing the questions
