You need to change the denominators so they are the same ( by timesing them together) E.g. 1/7 1/2 7x2=14

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.

When adding or subtracting fractions with different denominators, the first step is to find a common denominator. This involves finding the least common multiple (LCM) of the two denominators. Once you have a common denominator, you can then add or subtract the numerators of the fractions accordingly.
The denominators are different, so find the equivalent fractions using the LCD , then add the fractions with the denominators.
Multiply or divide both the numeraters and the denominators the same using GCF.Then look at the numeraters. Good luck!!!!!!!
