When adding fractions with unlike denominators it is most helpful if the fractions are renamed using the?
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.
How do you add fraction with common denominators?
To add fractions w/ common denominators, like 2/5 + 1/5, you must ONLY add the numerator, or the top numeral.
How do you add three fractions with unlike denominators?
