Question

Hii help I to lazy to do it

Answer 1

3 cans

Explanation:

3*9 1/9=27.3 meters^2

the closest number of cans for 27.3 meters^2 is 3 because

1 can=10 meters^2

2 cans=20 meters^2

3 cans=30 meters^2

so by estimating 3 cans would be the closest compared to 20 and 10.

Answer 2

3 cans

Explanation:

We need to find the area of the deck

A = 9 1/9 * 3

Changing to an improper fraction

9 1/9 = (9*9+1)/9 = 82/9

A = 82/9 *3 = 82/3

Changing back to a mixed number

82/3 = 27 1/3

Each can covers 10 m^2

We will need 3 cans
