Question

Simplify. -4/15-3/5=

Answer 1

`-(13)/(15)`

Explanation:

We need a common denominator.

The least common multiple of 15 and 5 is 15.

We change the second fraction to have 15 in the denominator.

`-(4)/(15) - (3)/(5) =`

`= -(4)/(15) - (3 * 3)/(3 * 5)`

`= -(4)/(15) - (9)/(15)`

`= -(13)/(15)`

Answer 2

-13/15

Explanation:

-4/15 - 3/5

Make common denominators by multiplying 3/5 by 3/3

-4/15 - (3/5 * 3/3)

-4/15 - 9/15

-13/15
