a machine takes 5.4 hours to make 9 parts. At that rate how many parts can the machine make in 25.8 hours

1 answer:

5 0

There are many ways to find the answer. One of them is to find how long does it take to make one part and then divide 25.8 by the result:

5.4 ÷ 9 = 0.6 (that's how long does it take to make one part)
25.8 ÷ 0.6 = <u>43</u> (that's how many parts can be made in 25.8 hours)
