Question

Identify which ratio is not equal to 3:2.


15:10


19:11


30:20


9:6

Answer 1

To determine which ratio is not equal to 3:2, we can simplify each ratio and compare it with 3:2.

1. **15:10**
Simplifying 15:10:
\( \frac{15}{10} = \frac{3}{2} \)
So, 15:10 = 3:2.

2. **19:11**
Simplifying 19:11:
\( \frac{19}{11} \) cannot be simplified further.
This ratio is not equal to 3:2.

3. **30:20**
Simplifying 30:20:
\( \frac{30}{20} = \frac{3}{2} \)
So, 30:20 = 3:2.

4. **9:6**
Simplifying 9:6:
\( \frac{9}{6} = \frac{3}{2} \)
So, 9:6 = 3:2.

Therefore, the ratio that is not equal to 3:2 is **19:11**.
