Earlier we looked at how to compare the size of numbers. Now, we are going to look at how we can create equal units of time and equal units of weight in the imperial system. This process is called conversion, which means to change from one unit to another without changing its size.
There are 60 seconds in 1 minute, so 60 seconds = 1 minute.
There are 60 minutes in 1 hour, so 60 minutes = 1 hour.
Lets watch on converting from a smaller unit of time to a larger unit of time:
Lets watch on converting from a larger unit of time to a smaller unit of time:
Now that we can convert between units of time, let's see how we convert between units of measure.
There are 16 ounces in 1 pound, so 16 ounces = 1 pound.
Fill in the blanks in the table. Express answers as fractions if needed.
|Pound (lb)||Ounce (oz)|
Convert $2$2 lb and $15$15 oz into ounces.
The walk to the letterbox and back takes $1$1 minute and $48$48 seconds.
How many seconds does the walk take in total?
