First, change 4 1/2 to 4 2/4 so that the two numbers have the same denominator.
4 2/4 - 1/4 = 4 1/4
My answer was 20 and 1/4
you find a common denominator, which is 4 in your case, and because you multiply 2 by 2 you have to multiply 41 by 2 as well, so you get 82/4-1/4, ok or do you need more help?
If the original problem is 41/2 not 4 1/2, you're right.
