Question

subtract 11/20 from -4/5 and add -9/10 to the answer​

Answer 1

Step-by-step explanation:

{-4/5 -(11/20) } + -9/10

LCM of 5,20 is 20

{-4/5 -(11/20) } = {-16-11/20}={-27/20}

{-27/20}+ -9/10

LCM of 20,10 is 20

-27+(-18)/20= -45/20

-45/20 is the answer

-9/4 is the simplest form of -45/20

Answer 2

Answer:

-9/5

Step-by-step explanation:

-4/5-(11/20) + (-9/10)

-4/5-11/20 - 9/20

LCM of 5, 20, 20 is 20

-4/5 * 4 = -16/20

So,

-16/20 - 11/20 - 9/20

-16-11-9/20

-36/20

-9/5
