hours in length. How many minutes did the teacher spend reviewing the worksheet? Enter your response as a decimal.
Turn 1 1/2 into a decimal.
Divide the decimal by 8, so you find 1/8 of 1 1/2.
Answer: 12 minutes
To find the number of minutes the teacher spent reviewing the worksheet, we need to convert the given class period length from hours to minutes and then multiply it by the fraction of the class period that was spent on reviewing.
Step 1: Convert class period length from hours to minutes
Since there are 60 minutes in 1 hour, we can multiply the class period length by 60 to convert it to minutes.
1 hour * 60 minutes/hour = 60 minutes
Step 2: Calculate the number of minutes spent reviewing the worksheet
We are told that 18 of the class period was spent reviewing the worksheet. To find the minutes spent reviewing, we need to multiply the fraction (18/100) by the total minutes in the class period.
Minutes spent reviewing = (18/100) * 60 minutes
Step 3: Simplify and calculate
To calculate the answer, we multiply the fraction (18/100) by 60 minutes and simplify the result.
Minutes spent reviewing = (18/100) * 60 minutes = 10.8 minutes
Therefore, the teacher spent 10.8 minutes reviewing the worksheet.
