ok this is like 5th grade math but you have to multiply. Say it is 1/4+3/8. You have to multiply the lower denominator which in this case is 4 to get it to 8. Which you get 4x2=8 right. Well whatever you do to the denominator you have to do to the numerator. so the numerator is 1 in the fraction of 1/4 and you get 1x2=2. So then your problem is 2/8+3/8= 5/8. If your worried that the denominator will not go into it dont because you will never get a problem like that

How is adding like fractions and adding unlike fractions the same?
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.
