The table shows the amount of time four different battery brands lasted in a toy train write the names of the batteries in order from least amount of time to most amount of time they lasted Duracell 2 2/3 Energizer 2.25 Eveready 1.75 Rayovac 2 7/12

Answer 1

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.

1. Eveready: 1.75 hours (which is equivalent to $\frac{7}{4}$).
2. Energizer: 2.25 hours (which is equivalent to $\frac{9}{4}$).
3. Duracell: 2 2/3 hours (which is $2+\frac{2}{3}=\frac{8}{3}$ or approximately 2.67 hours).
4. Rayovac: 2 7/12 hours (which is $2+\frac{7}{12}=\frac{31}{12}$ or approximately 2.58 hours).

Now we need to find a common denominator to compare:

• $\frac{7}{4}$ (1.75)
• $\frac{9}{4}$ (2.25)
• $\frac{8}{3}\approx 2.67=\frac{32}{12}$
• $\frac{31}{12}\approx 2.58$

Now let's write these out:

1. Eveready: 1.75 hours
2. Rayovac: $2\frac{7}{12}$ or approximately 2.58 hours
3. Energizer: 2.25 hours
4. Duracell: $2\frac{2}{3}$ or approximately 2.67 hours

Now, the correct order from least amount of time to most amount of time is:

1. Eveready
2. Rayovac
3. Energizer
4. Duracell
