Dont know the question or options but.....

I would round up to the nearest 10...

so 30 into 630 is 21............. if this multiple choice then you can find the nearest one

Hi lostin11plus

Welcome!

Could you post an exact question, and then we will do our best. (Although I suspect it won't be me providing the answer!)

Use the skills you have, lay out in two columns,

ten lots of 28 is 280
so
twenty lots 28 is 560
twenty two lots of 28 is 560+56=616

etc.
