Question

Stefanie is painting her bedroom. She can paint 12 2/3 square feet in 2/5 of an hour. How many square feet can she paint in one hour?

Answer 1

The answer is 31 2/3

Answer 2

`31(2)/(3)`

Explanation:

since its only 2/5 of 1 hour, two 2/5 equal 4/5 so we divide the 12 2/3 by 2 to find the 1/5 which is 6 1/3

`12(2)/(3)`÷2=
`6(1)/(3)`

`12(2)/(3) +12(2)/(3)=25(1)/(3)`

`12(1)/(3) +6(1)/(3)=31(2)/(3)`
