Answer 2

To solve these division problems, we can convert the decimal numbers to fractions and then perform the division. Here are the solutions to the given division problems:

1. 0.065 ÷ 0.02: Convert to fractions: 0.065 = 65/1000 and 0.02 = 2/100 Divide the fractions: (65/1000) ÷ (2/100) = (65/1000) × (100/2) = (65 × 100) / (1000 × 2) = 6500 / 2000 = 13/4 = 3.25

2. 49 ÷ 2.8: Convert to fractions: 49/1 ÷ 2.8/1 = 49/1 × 1/2.8 = (49 × 1) / (1 × 2.8) = 49/2.8 = 17.5

3. 14.28 ÷ 1.19: Convert to fractions: 14.28 = 1428/100 and 1.19 = 119/100 Divide the fractions: (1428/100) ÷ (119/100) = (1428/100) × (100/119) = (1428 × 100) / (100 × 119) = 142800 / 11900 = 12

4. 0.1995 ÷ 0.15: Convert to fractions: 0.1995 = 1995/10000 and 0.15 = 15/100 Divide the fractions: (1995/10000) ÷ (15/100) = (1995/10000) × (100/15) = (1995 × 100) / (10000 × 15) = 199500 / 150000 = 1.33

5. 7.156 ÷ 0.01: Convert to fractions: 7.156 = 7156/1000 and 0.01 = 1/100 Divide the fractions: (7156/1000) ÷ (1/100) = (7156/1000) × (100/1) = (7156 × 100) / (1000 × 1) = 715600 / 1000 = 715.6

6. 60.716 ÷ 1.18: Convert to fractions: 60.716 = 60716/1000 and 1.18 = 118/100 Divide the fractions: (60716/1000) ÷ (118/100) = (60716/1000) × (100/118) = (60716 × 100) / (1000 × 118) = 6071600 / 118000 = 51.43

So, the solutions to the given division problems are:

1. 0.065 ÷ 0.02 = 3.25
2. 49 ÷ 2.8 = 17.5
3. 14.28 ÷ 1.19 = 12
4. 0.1995 ÷ 0.15 = 1.33
5. 7.156 ÷ 0.01 = 715.6
6. 60.716 ÷ 1.18 = 51.43
