Question

How do you evaluate `\frac { 7} { 16} + \frac { 3} { 8} - \frac { 1} { 2}`?

Answer 1

`5/16`

Explanation:

First, to solve this you need all of them to have a common denominator, usually the "LCD (Lowest Common Denominator)". The LCD here would be 16.
So it looks like this now:
`7/16 + 6/16 - 8/16`

Now, you can place them all on top of one denominator like this:
`(7 + 6 - 8)/16`
And solve it like a normal adding problem:
`5/16`
