To determine the correct order of the divers from least to greatest amount of oxygen left in their tanks, let's convert all the given oxygen amounts to decimal form for easier comparison.
1. Alexis:
[tex]\[
\frac{71}{9} = 7.888\ldots \approx 7.89
\][/tex]
2. Dante:
[tex]\[
7.5
\][/tex]
3. Sofia:
[tex]\[
7 \frac{5}{8} = 7 + \frac{5}{8}
\][/tex]
[tex]\[
\frac{5}{8} = 0.625
\][/tex]
[tex]\[
7 + 0.625 = 7.625
\][/tex]
Now that we have the decimal representations of the oxygen amounts:
- Alexis: 7.89
- Dante: 7.5
- Sofia: 7.625
Next, we compare these values to order them from least to greatest:
- Dante has 7.5 liters,
- Sofia has 7.625 liters,
- Alexis has 7.89 liters.
The correct order from least to greatest based on the amount of oxygen left is:
1. Dante (7.5 liters)
2. Sofia (7.625 liters)
3. Alexis (7.89 liters)
Thus, the final order is:
- Dante, Sofia, Alexis.
Therefore, the answer is:
1. Dante, Sofia, Alexis
