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

Liono4ka [1.6K]

Answer:

-7/45

Step-by-step 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.

$-\frac{8}{9} +\frac{11}{15}$

$= -\frac{8*5}{9*5} +\frac{11*3}{15*3}$ Since 15*3=45, multiply the top by 3 also. Since 9*5=45, multiply the top by 5 also.

$= -\frac{40}{45} +\frac{33}{45}$

$= \frac{-40+33}{45}$ Combine the fractions

$= -\frac{7}{45}$ Answer in lowest terms
