Answer:
30%
Step-by-step explanation:
Let's first convert the 2.5 hours into minutes so we have the same units.
1 hour = 60 minutes
2.5 x 60 = 150 minutes
Now we can use the percentage formula.
(value/total value) x 100 = percentage
Since the question is asking what percent of 2½ hours is 45 minutes, we plug in the formula like this.
(45/150) x 100 = 30%
tadah!
