Answer 2

To multiply fractions, you simply multiply the numerators together and multiply the denominators together. Let's solve each of the given multiplications step by step:

1. 1/8 * 19/7 Result: (1 * 19) / (8 * 7) = 19 / 56

2. 26/3 * 2/3 Result: (26 * 2) / (3 * 3) = 52 / 9

3. 3/5 * 20/15 Before multiplying, let's simplify the fractions: 3/5 = (3 * 1) / (5 * 1) = 3 / 5 20/15 = (20 * 1) / (15 * 1) = 20 / 15

   Now, multiply: (3 * 20) / (5 * 15) = 60 / 75 Simplify the result: 60 / 75 = (60 ÷ 15) / (75 ÷ 15) = 4 / 5

4. 2/7 * 14/19 Result: (2 * 14) / (7 * 19) = 28 / 133

5. 8/25 * 5/16 Before multiplying, let's simplify the fractions: 8/25 = (2 * 4) / (5 * 5) = 2/5 5/16 = 5 / (2 * 8) = 5 / 16

   Now, multiply: (2 * 5) / (5 * 16) = 10 / 80 Simplify the result: 10 / 80 = (10 ÷ 10) / (80 ÷ 10) = 1 / 8

6. 13/11 * 11/13 These fractions are reciprocals of each other, and their product is always 1.

7. 26/49 * 7/13 Result: (26 * 7) / (49 * 13) = 182 / 637

8. 17/18 * 4/17 These fractions are also reciprocals of each other, and their product is 1.

9. 14/45 * 50/21 Before multiplying, let's simplify the fractions: 14/45 = (2 * 7) / (3 * 5 * 3) = 2/15 50/21 = (2 * 5 * 5) / (3 * 7) = 10/7

   Now, multiply: (2 * 10) / (15 * 7) = 20 / 105 Simplify the result: 20 / 105 = (20 ÷ 5) / (105 ÷ 5) = 4 / 21

10. 36/49 * 7/12 Before multiplying, let's simplify the fractions: 36/49 = (4 * 9) / (7 * 7) = 4/7 7/12 = 7 / (3 * 4) = 7 / 12

    Now, multiply: (4 * 7) / (7 * 12) = 28 / 84 Simplify the result: 28 / 84 = (28 ÷ 28) / (84 ÷ 28) = 1 / 3

So, the results of the given multiplications are:

1. 1/8 * 19/7 = 19/56
2. 26/3 * 2/3 = 52/9
3. 3/5 * 20/15 = 4/5
4. 2/7 * 14/19 = 28/133
5. 8/25 * 5/16 = 1/8
6. 13/11 * 11/13 = 1
7. 26/49 * 7/13 = 182/637
8. 17/18 * 4/17 = 1
9. 14/45 * 50/21 = 4/21
10. 36/49 * 7/12 = 1/3
