What is the decimal for 45 minutes?
(Please don't say 0.45!!!)
Remember that there are 60 minutes in an hour. Since 60 minutes = 1 hour, we can create a fraction with 60 as the denominator.
In this case:
45
60
Or in more general (algebraic) terms:
m if m = number of minutes
60
Once you have a fraction, it is time to convert to a decimal.
Since
45 = 45 / 60 = 0.75
60
The answer should be 0.75 parts of an hour,
but what if I divided wrong?
Better check my work.
Think back early elementary school when you were first learning about fractions. Remember when you were first cutting up a circle. You probably had these pieces.
Picture 1 shows
1 = 0.25
4
Picture 2 shows
1 = 0.5
2
Picture 3 shows
3 = 0.75
4
Since 45 minutes is like the 3/4 clock,
45 minutes = 0.75.
Yes! That matches the answer from dividing!
