Gre4nikov [31]

Answer:

7/20 of one shelf in an hour

Step-by-step explanation:

if you think about the problem in numbers out of 100, we know that

- 2/3 of an hour is 40 minutes per hour because 60/3 = 20

- 1/4 of a shelf is 25% of the shelf

In an hour Leland can build 35% of a shelf in an hour or 7/20 of a shelf
