Question

Hi, it's me!
How to add fractions with unequal denominators?

Answer 1

u take the fractions denominator and find a common number (as low as possible) that they both can multiply into and you then multiply the top numbers by whatever the bottom numbers of the same fraction multiply into.

Answer 2

Adding Fractions with Unlike Denominators

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.

For example, suppose you want to add:

111+23

1/11 + 2/3

The LCM of 3 and 11 is 33 . So, we need to find fractions equivalent to 111 and 23 which have 33 in the denominator. Multiply the numerator and denominator of 111 by 3 , and multiply the numerator and denominator of 23 by 11 .

(1 × 311 × 3)+(2 × 113 × 11)=333+2233

Now we have like denominators, and we can add as described above.

=2533
