Here is another answer that I need reviewed.
It takes a machine 3 minutes to fill 20 bottles of soda. At this rate how many minutes will it take the machine to fill 48 bottles of soda?
1. (3min/20 sodas)=(m/48 sodas)
3. 48/6.6666667=7.2 minutes
My question is should the answer be 7.2 minutes or should I round it to 7 minutes? The question does not state if it wants the exact answer or a rounded full minute. Thanks in advance everyone.
Unless they ask you to round it I would leave it as 7.2 min
Some people may leave it as a fraction, hence,
a da the previous step is 36/5, and I like fractions, I would leave it as 36/5...
Just because a number is written as a decimal doesn't mean it is rounded.
7.2 minutes is not a rounded answer because the answer is exactly 7.2 minutes.
