Aleaky pool loses 2 1/4 inches of water each day. jermaine and mildred are asked to determine the change in the amount of water in the pool over 5 days.

mildred’s solution
5 (-2 1/4)
5(-2- 1/4)
-10-5/4
-11 1/4

5(-2 1/4)

Step-by-step explanation: When somethig is being taken away, it's represented as a negative number. The number needs to be displayed throug 5 days, so A would be correct. To check, a negative times a postive is a negative, and 5 times -2 1/4 is -11 1/4.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
