make all fractions have the same denominator (bottom number) and then do the math.
1/2 = 1/2
2/1 = 4/2
-1/2 + 4/2 = 3/2 = 1.5

When adding fractions, they must be in terms of a common denominator...in this case, the denominator is 2
- Multiply 2/1 *2/2 = 4/2
Then add: -1/2 + 4/2
Simplify using the common denominator: (-1+4)/2
Perform the addition (-1+4) = 3
Final Answer : 3/2
Good Luck

change these fractions to a decimal point and then add the numbers. then convert it back to a fraction if u have to, for example, 1/2 is equal to 0.5 and 1/10 is 0.1. i find it much easier this way!
