Question

Add -1
`(1)/(4)` 0.75 +0.45. Write your answer as a decimal to the nearest hundredth.

Answer 1

Explanation:

-0.05

Answer 2

Answer: -1/20, or -0.05

Explanation:

rewrite -1 1/4 as -5/4

rewrite 0.75 as 75/100 and simplify = 3/4

rewrite 0.45 as 45/100 and simplify = 9/20

-5/4+3/4 = -2/4 = -1/2

-1/2+9/20 find LCD

LCD = 20

-1/2 * 10/10

-10/20+9/20= -1/20
