it is just what it sounds like... you take 2 or more fractions and add them. So 1/2 and 1/2 =2/2 or1
adding fractions r easy math prblems. like 1/4 +1/4 = 1/2.
When you are multiplying with mixed number fractions, it becomes easier to work with improper fractions instead. For example, 2 1/3 x 1 1/2 (two and a third times one and a half) is 2 x 1 + 2 x 1/2 + 1/3 x 1 + 1/3 x 1/2 But with improper fractions, it's 7/3 x 3/2 = 7/2 = 3 1/2
You must have 2 fractions or more to have unlike fractions. They are fractions with different denominators such as 7/8 and 1/2. Like fractions would have the same denominator like 7/8 and 4/8.
They are 1/7 and 2/14
