Question

Explain the rules for multiplication and division to convert units. How do you know when to multiply and when to divide to convert units of measurement?

Write three to four sentences.

Answer 1

You understand how some units are larger or smaller than other units, right? Like how hours are larger than minutes and minutes are larger than seconds, but they all measure the same thing.

When converting between units like that, you would multiply to convert a larger unit to a smaller unit, and divide to convert a smaller unit to a larger unit, depending on the difference.

For example, there are 60 minutes in an hour. So, if we want to convert 300 minutes to one hour, we would divide: 300 minutes/60 minutes per hour = 5 hours
Conversely, if we have 10 hours and want to find out how many minutes that is, we multiply: 10 hours * 60 minutes per hour = 600 minutes

I hope this explanation and the examples can help you understand, so you'll be able to write your own response to the Question.
