Question 1: Express the following rational numbers as decimals.
(i) 42/100 (ii) 327/500 (iii) 15/4

Let's convert each of the given rational numbers to decimal form.

**(i) \( \frac{42}{100} \):**
\[
\frac{42}{100} = 0.42
\]
So, \( \frac{42}{100} = 0.42 \).

**(ii) \( \frac{327}{500} \):**
To convert this fraction to decimal, divide 327 by 500:
\[
\frac{327}{500} = 0.654
\]
So, \( \frac{327}{500} = 0.654 \).

**(iii) \( \frac{15}{4} \):**
To convert this fraction to decimal, divide 15 by 4:
\[
\frac{15}{4} = 3.75
\]
So, \( \frac{15}{4} = 3.75 \).

### Summary:
- \( \frac{42}{100} = 0.42 \)
- \( \frac{327}{500} = 0.654 \)
- \( \frac{15}{4} = 3.75 \)
