Write the ratio in the simplest form 60:80 , 15:5 , 7:21 ,4:6 , 16:20

To simplify a ratio, we divide both terms by their greatest common divisor (GCD). Let’s simplify each ratio step by step:

1. **\( 60:80 \)**
   - GCD of 60 and 80 is 20.
   - Simplified: \( \frac{60}{20} : \frac{80}{20} = 3:4 \).

2. **\( 15:5 \)**
   - GCD of 15 and 5 is 5.
   - Simplified: \( \frac{15}{5} : \frac{5}{5} = 3:1 \).

3. **\( 7:21 \)**
   - GCD of 7 and 21 is 7.
   - Simplified: \( \frac{7}{7} : \frac{21}{7} = 1:3 \).

4. **\( 4:6 \)**
   - GCD of 4 and 6 is 2.
   - Simplified: \( \frac{4}{2} : \frac{6}{2} = 2:3 \).

5. **\( 16:20 \)**
   - GCD of 16 and 20 is 4.
   - Simplified: \( \frac{16}{4} : \frac{20}{4} = 4:5 \).

**Simplified Ratios:**

- \( 60:80 = 3:4 \)
- \( 15:5 = 3:1 \)
- \( 7:21 = 1:3 \)
- \( 4:6 = 2:3 \)
- \( 16:20 = 4:5 \)
