Question

1. Express the following according to the 24 - hour clock : $$ \begin{array}{lll}	ext { (a) } 10: 15 \mathrm{a} . \mathrm{m} & 	ext { (b) } 9: 05 \mathrm{a} . \mathrm{m} & 	ext { (c) } 10: 00 \mathrm{a} . \mathrm{m} \ 	ext { (e) } 6: 20 \mathrm{p} . \mathrm{m} & 	ext { (f) } 9: 45 \mathrm{p} . \mathrm{m} & 	ext { (g) } 11: 10 \mathrm{p} . \mathrm{m} \ 	ext { (i) } 12: 15 \mathrm{p} . \mathrm{m} & 	ext { (j) } 12: 35 \mathrm{a} . \mathrm{m} & \end{array} $$

Sure! Here are the times expressed in the 24-hour clock format:

$$
\begin{array}{lll}
\text{(a)}\ 10:15 \ \text{a.m.} & =\ 10\:15 \
\text{(b)}\ 9:05 \ \text{a.m.} & =\ 09\:05 \
\text{(c)}\ 10:00 \ \text{a.m.} & =\ 10\:00 \
\text{(e)}\ 6:20 \ \text{p.m.} & =\ 18\:20 \
\text{(f)}\ 9:45 \ \text{p.m.} & =\ 21\:45 \
\text{(g)}\ 11:10 \ \text{p.m.} & =\ 23\:10 \
\text{(i)}\ 12:15 \ \text{p.m.} & =\ 12\:15 \
\text{(j)}\ 12:35 \ \text{a.m.} & =\ 00\:35 \
\end{array}
$$

**Explanation:**

- **a, b, c:** Times in the morning (a.m.) remain the same, except leading zeros are added if necessary.
- **e, f, g:** Times in the evening (p.m.) are converted by adding 12 to the hour component.
- **i:** 12:15 p.m. remains 12:15 in 24-hour format.
- **j:** 12:35 a.m. is midnight plus 35 minutes, which is represented as 00:35.
Here are the times in 24-hour format: - (a) 10:15 a.m. = 10:15 - (b) 9:05 a.m. = 09:05 - (c) 10:00 a.m. = 10:00 - (e) 6:20 p.m. = 18:20 - (f) 9:45 p.m. = 21:45 - (g) 11:10 p.m. = 23:10 - (i) 12:15 p.m. = 12:15 - (j) 12:35 a.m. = 00:35
