Answer 1

To find the ratio of boys to girls in the chorus, we can express it as:

\[
\text{Ratio of boys to girls} = \frac{\text{Number of boys}}{\text{Number of girls}} = \frac{12}{20}
\]

Next, we simplify this fraction. Both the numerator and the denominator can be divided by 4:

\[
\frac{12 \div 4}{20 \div 4} = \frac{3}{5}
\]

Thus, the ratio of boys to girls is \(3:5\).

The correct response is:

**3:5**
**3 colon 5**
