So you're looking for 2 numbers you can divide to get ABOUT 4.1. This means you're going to estimate. First you can estimate that 4.1 is about 4 and then think what two numbers divide to give you 4? 8÷2 = 4 ... so now we can change it slightly to make the quotient a little higher and say
8.1÷2 = 4.05 That will round to 4.1 so you could say two numbers who's quotient is ABOUT 4.1 would be...
8.1 and 2
