Question

How do you simplify `5/7+31/3`?

Answer 1

See full simplification process below:

Explanation:

To add two fractions they must be over a common denominator, in this case 21. To put the two fractions over common denominators we must multiply each fraction by the appropriate form of `1`:

`5/7 + 31/3 = (3/3 xx 5/7) + (7/7 xx 31/3) = 15/21 + 217/21`

We can now add the numerators over the common denominator:

`15/21 + 217/21 = (15 + 217)/21 = 232/21`
