Question

I need help ASAP! How to solve addition with unlike denominators someone help!!

Answer 1

Make them have a common denominator.
Ex: 2/3 + 1/2
The lowest common multiple of the denominators 3 (3,6..) and 2 (2, 4, 6..) is 6. Multiply each fraction by whatever you had to multiple it by to get the common multiple.
2(2/3) + 3(1/2)
4/6 + 3/6 = 7/6 or 1 1/6 (mixed fraction)

Answer 2

You multiply by common factors. For example, 4/8 + 3/4:

We can multiply 3/4 by 2/2 so that 4 becomes 8, so we get:

4/8 + 3/4(2/2) or 4/8 + 6/8 = 10/8
