Question

I need help finding the lowest term for -8/9+11/15​

Answer 1

-7/45

Explanation:

First, find the lowest common denominator for 9 and 15. It's 45. Make both fractions over 45 by multiplying the top and bottom by the same number.

`-(8)/(9) +(11)/(15)`

`= -(8*5)/(9*5) +(11*3)/(15*3)` Since 15*3=45, multiply the top by 3 also. Since 9*5=45, multiply the top by 5 also.

`= -(40)/(45) +(33)/(45)`

`= (-40+33)/(45)` Combine the fractions

`= -(7)/(45)` Answer in lowest terms
