Simple. If you find that one of the denom. goes into the other one, evalute them so the denom. are the same and their numerators are possibly different. Example:
7/42 + 3/6
3/6 = 21/42
21+7=28
ANSWER: 28/42

How do you put the following fractions from least to greatest when the denominators are different?
Multiply or divide both the numeraters and the denominators the same using GCF.Then look at the numeraters. Good luck!!!!!!!
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.
What is three eighths plus one fourth?
The denominators are different, so find the equivalent fractions using the LCD , then add the fractions with the denominators.
How do you subtract fractions with like denominators?
Subtract the numerators as we normally subtract them and then divide the resultant by the denominator. It's just simple like that.
Adding fractions with different denominators?
You need to change the denominators so they are the same ( by timesing them together) E.g. 1/7 1/2 7x2=14
