Question

Select all ratios equivalent to 16:3.
11:7
80:15
12:5

Answer 1

To determine which of the given ratios are equivalent to 16:3, we can simplify or compare each ratio with 16:3.

1. **For 11:7**:
\[ \frac{11}{7} \] is not equivalent to \(\frac{16}{3}\) because \( \frac{11}{7} = 1.571 \) and \( \frac{16}{3} = 5.333 \).

2. **For 80:15**:
We can simplify \( \frac{80}{15} \):
\[ \frac{80 \div 5}{15 \div 5} = \frac{16}{3} \]
This is equivalent to 16:3.

3. **For 12:5**:
\[ \frac{12}{5} \] is not equivalent to \(\frac{16}{3}\) because \( \frac{12}{5} = 2.4 \) and \( \frac{16}{3} = 5.333 \).

Thus, the only ratio equivalent to 16:3 is:
- **80:15**.
