Question

How do you simplify `n/2 - n/7`?

Answer 1

`(5n)/14`

Explanation:

We need to resolve these into a single fraction. The lowest common multiple of 2 and 7 is 14. We multiply the numerator and denominator of each fraction by the amount required to get the denominator to 14.

`n/2 - n/7`

`n/2*7/7 - n/7*2/2`

`(7n)/14 - (2n)/14 = (5n)/14`
