So you would start with 40/n because quotient means division and then it would be (40/n) - 13 (40 divided by n then minus 13) because the answer is thirteen less than the quotient of those numbers. since it wants you to evaluate for n=2 you would do 40/2 which is 20 then subtract 13 which is 7.
So write the expression as (40/n) -13 and when you evaluate just stick the 2 where the n is for (40/2) - 13 20 - 13 = 7
40. 40 ------ -13 ------ -13. 20-13. 7 N 2 You would write this this by just looking at the key terms like for example (13 less than) which means it's being subtracted. And (quotient of 40 and a number) means that it's going to be a fraction with 40 at the top and n on the bottom. It's really simple once you get practice hope this helps :)
