To order the battery brands from least amount of time to most amount of time, we first need to convert the mixed numbers to improper fractions or decimals for easier comparison.
- Eveready: 1.75 hours (which is equivalent to
). - Energizer: 2.25 hours (which is equivalent to
). - Duracell: 2 2/3 hours (which is
or approximately 2.67 hours). - Rayovac: 2 7/12 hours (which is
or approximately 2.58 hours).
Now we need to find a common denominator to compare:
(1.75) (2.25)
Now let's write these out:
- Eveready: 1.75 hours
- Rayovac:
or approximately 2.58 hours - Energizer: 2.25 hours
- Duracell:
or approximately 2.67 hours
Now, the correct order from least amount of time to most amount of time is:
- Eveready
- Rayovac
- Energizer
- Duracell
