multiply them then divide
About eight pounds.
You divide 20 by 5, which is four. You then multiply 4 by the amount of pounds (2).
Hope that helps
You would round the numbers to 830 and 20 and divide, that’d be 41.5, that’s your estimate. Then divide 828 and 23, that’d be 36. That’s your answer. Oh and to check your answer, 23 times 36=828
