Answer:

2 and 38/45 square yards can be sanded in 3.2 hours.

Step-by-step explanation:

1/2 of an hour is 30 minutes. so 4/9 for every 30 minutes. 1 hour is 8/9. So 3 2/10 would be 3 hours =24/9=2 6/9 and 2/10 would be ( if 5/10 is 30 minutes then 2/10 is 12 minutes.) 8/9 x 1/5 = 8/45. (24 x 5 = 120) 120/45 + 8/45 is 128/45 = 2 38/45

The square yards you can sand in 3.2 hours is 2.85 square yards

4/9 square wood= 1/2 hour

x= 1hour

4/9= 1/2x

x=  4/9 ÷ 0.5

= 0.444 ÷ 0.5

= 0.89

1 hour= 0.89 square yards

3.2 hours= x

Cross multiply

x= 2.848

Hence the square yards you can sand in 3.2 hours is 2.85 square yards
