How do you solve math problems that are a fraction equals a fraction plus or minus a fraction?

Answer 1

You have to find the fraction's common denominators so you can combine them. For instance, 7/12=1/3+1/4. The common denominator between 12, 3, and 4 is 12. So you must make every fraction into twelfths. 3*4=12, so 1*4=4. So, 1/3=4/12. Then, 4*3=12, so 1*3=3. So, 1/4=3/12. So, 4/12+3/12=7/12.
