Answer 2

Let's solve each of these calculations step by step:

1. 5/6 * 3/20: To multiply fractions, you simply multiply the numerators together and the denominators together. (5/6) * (3/20) = (5 * 3) / (6 * 20) = 15 / 120 = 1/8

2. 8 3/4 * 1 3/14: First, convert mixed numbers to improper fractions. 8 3/4 = (4 * 8) + 3 = 35/4 1 3/14 = (14 * 1) + 3 = 17/14 Now, multiply the two fractions. (35/4) * (17/14) = (35 * 17) / (4 * 14) = 595 / 56 = 10 15/56

3. 8/15 : 24: To divide fractions, you invert the second fraction and then multiply. (8/15) : 24 = (8/15) * (1/24) = 8 / (15 * 24) = 2 / 45

4. 6 * 7/18: To multiply a whole number by a fraction, you can convert the whole number to a fraction with the same denominator as the fraction, and then multiply. 6 * (7/18) = (6 * 18) / 18 * (7/18) = 42/18 = 7/3

5. 2/3 : 11/3: Division of fractions works the same way as multiplying by the reciprocal. (2/3) : (11/3) = (2/3) * (3/11) = 6 / 33 = 2/11

6. 1 3/5 : 5 1/3: Convert the mixed numbers to improper fractions. 1 3/5 = (5 * 1) + 3 = 8/5 5 1/3 = (3 * 5) + 1 = 16/3 Divide the two fractions. (8/5) : (16/3) = (8/5) * (3/16) = 24 / 80 = 3/10

So, the results of the calculations are:

1. 1/8
2. 10 15/56
3. 2/45
4. 7/3
5. 2/11
6. 3/10
