Time is a continuous sequence of existence that occurs in everyday life. We have to learn how to calculate time in addition, subtraction, multiplication, and division. In the previous article, we have learned about adding and subtracting time. In this article, we will learn about multiplication and division of time with examples. A simple method to calculate the time with multiplication and division is shown in this article. Hence students can refer to our page to enhance their skills and also to score the best grades in the exams.
How to Multiply Time?
The students of grade 5 can learn how to multiply Time in Hours and Minutes, and seconds from the smallest unit to the largest units of time.
1. Multiply each unit of time by the multiple.
2. If the seconds are greater than 59, then divide by 60 to get a whole number and remainder.
3. Keep the remainder as total seconds and add the units of time.
4. If the greater than 59, divide by 60 to get a whole number and remainder.
5. Keep the remainder as total minutes and add the numbers to hours.
6. If the hours are greater than 23, divide by 24 to get the number and remainder.
How to Divide Time?
Learn how to divide hours, minutes, and seconds from the below steps.
1. Divide each unit of time by the divisor.
2. Convert from largest to smallest unit of time.
3. Keep the whole number from days to hours.
4. 1 day = 24 hours, multiply the decimal by 24, and then add the results to hours.
5. Now convert from hours to minutes.
6. 1 hour = 60 minutes, multiply the decimal by 60, and then add to minutes.
7. And then convert from minutes to seconds.
8. 1 minute = 60 seconds, multiply the decimal by 60, and then add to seconds.
Multiplication and Division of Time Examples
Go through the below examples to find the multiplication and division of time in a simple method.
Example 1.
Multiply 4 hours 20 minutes by 5.
Solution:
First, multiply minutes with 5
20 minutes × 5 = 100 minutes
Convert 100 minutes into hours
60 minutes = 1 hour
100 minutes = 60 minutes + 40 minutes = 1 hour 40 minutes
Multiply the hours
4 hours × 5 = 20 hours
Then total time = 1 hour 40 minutes + 20 minutes = 1 hour 60 minutes
60 minutes = 1 hour
So the total time is 2 hours.
Therefore 4 hours 20 minutes multiply 5 = 2 hours
Example 2.
Divide 4 hours 8 minutes by 2.
Solution:
Convert 4 hours 8 minutes into minutes
4 hours 8 minutes = 4 × 60 + 8 minutes
= 240 + 8 minutes
= 248 minutes
248 minutes divided by 2 = 124.
Therefore 4 hours 8 minutes by 2 = 124 minutes
Example 3.
Multiply 4 minutes 2 seconds by 8.
Solution:
First, multiply the seconds by 8
2 seconds × 8 = 16 seconds
Multiply the minutes
multiply 4 minutes × 8 = 32 minutes
Total 4 minutes 2 seconds by 2 = 32 minutes + 16 seconds = 32 minutes 16 seconds
Therefore 4 minutes 2 seconds by 8 = 32 minutes 16 seconds.
Example 4.
Multiply 2 weeks 10 days by 4
Solution:
First, multiply the days by 4
10 days × 4 = 40 days
Convert days into weeks
7 days = 1 week
So, 40 days = 5 weeks 5 days
Multiply the weeks by 4
2 weeks × 4 = 8 weeks
Total time = 5 weeks 5 days + 8 weeks = 13 weeks 5 days
Therefore 2 weeks 10 days by 4 = 13 week 5 days.
Example 5.
Divide 5 weeks 4 days by 3
Solution:
Convert 5 weeks 4 days into days
1 week = 7 days
5 × 7 = 35 days
5 weeks 4 days = 35 days + 4 days = 39 days
Divide 39 by 3 = 13 days
Therefore 5 weeks 4 days divided by 3 = 13 days.
