Question

One day,students in Mr. Tate’s science lab noticed a strange moss growing on a cabinet. During the next few days, the moss grew quickly, covering desks,chairs,and the floor. Each day, the class recorded the growth of the moss. 1 on the first day, the moss covered 1 1/2 square feet. On the second day, it covered a total of 3 3/4 square feet.how much more surface did the moss cover on the second day?

Answer 1

`(9)/(4)\ or\ 2(1)/(4)\ square feet`

Explanation:

On the first day the moss covered

`=1(1)/(2)\ square feet`

`=(3)/(2)\ square\ feet`

One the second day the moss covered
`=3(3)/(4)` square feet

`=(15)/(4)\ square\ feet`

Extension of moss cover on second day

= Moss covered second day - Moss covered first day

`=(15)/(4)-(3)/(2)\\=(15)/(4)-(3*2)/(2*2) \\=(15)/(4)-(6)/(4)\\=(9)/(4) \\=2(1)/(4)\ square\ feet`
