Question

Ann cleans 9 vessels in 10 minutes and her friend Kathy cleans 12 vessels in 14 minutes. Who cleans less number of vessels?

Answer 1

To find out who cleans fewer vessels, we can calculate the number of vessels each person cleans per minute and compare them.

**For Ann:**
- Ann cleans 9 vessels in 10 minutes.
- Therefore, the rate at which Ann cleans is:

\[
\text{Rate of Ann} = \frac{9 \text{ vessels}}{10 \text{ minutes}} = 0.9 \text{ vessels per minute}
\]

**For Kathy:**
- Kathy cleans 12 vessels in 14 minutes.
- Therefore, the rate at which Kathy cleans is:

\[
\text{Rate of Kathy} = \frac{12 \text{ vessels}}{14 \text{ minutes}} = \frac{12}{14} \text{ vessels per minute} = \frac{6}{7} \text{ vessels per minute} \approx 0.857 \text{ vessels per minute}
\]

Now we can compare their cleaning rates:

- Ann cleans at a rate of 0.9 vessels per minute.
- Kathy cleans at a rate of approximately 0.857 vessels per minute.

Since 0.857 is less than 0.9, Kathy cleans fewer vessels per minute than Ann.

Thus, **Kathy cleans fewer vessels.**
