Answer 1

To determine which ratios are equivalent to 1:4, we can simplify each of the given ratios and see if they reduce to 1:4.

1. **5:20**:
- Simplifying 5:20:
\[
\frac{5}{20} = \frac{1}{4}
\]
This is equivalent to 1:4.

2. **4:16**:
- Simplifying 4:16:
\[
\frac{4}{16} = \frac{1}{4}
\]
This is also equivalent to 1:4.

3. **3:12**:
- Simplifying 3:12:
\[
\frac{3}{12} = \frac{1}{4}
\]
This is equivalent to 1:4 as well.

Therefore, all the ratios provided (5:20, 4:16, and 3:12) are equivalent to 1:4.
