Answer 3

To convert the given ratios into fractions, we can use the following notation: "a:b/c" represents "a + b/c." Now let's convert each of the ratios into fractions:

1. 7:1/7 = 7 + 1/7 = (7 * 7 + 1)/7 = 50/7

2. 6:3/5 = 6 + 3/5 = (6 * 5 + 3)/5 = 33/5

3. 1:2/7 = 1 + 2/7 = (1 * 7 + 2)/7 = 9/7

4. 1:24/25 = 1 + 24/25 = (1 * 25 + 24)/25 = 49/25

Therefore, the ratios expressed as fractions are:

1. 7:1/7 = 50/7
2. 6:3/5 = 33/5
3. 1:2/7 = 9/7
4. 1:24/25 = 49/25
