2m + n
(2 * 2/5) + 1/2 = 4/5 + 1/2
4/5 + 1/2 = 8/10 + 5/10 = 13/10 = 1 3/10
I'll be glad to check your work for the second problem.
Evaluate for each expression m = 2/5 and n = 1/2
1) 2m + n
2) 2m - n
Please explain so I can understand the rest of the questions.

Replace the m's with 2/5 and the n's with 1/2
2 multiplied times 2/5 + 1/2
2/1 times 2/5 = 4/5
4/5 + 1/2 you need a common denominator of 10 to finish the problem
8/10 + 5/10 = 13/10 or 1 3/10
Do the same thing for #2, but you will be subtracting 5/10 from 8/10

1. 2(2/5) + 1/2 = 4/5 + 1/2 = .8 + .5 = 1.3 = 1 3/10
2. Using the information above, you should be able to do this one yourself.
