Answer 1

Ответ:

9/2 * 21/4 = 189/8 = 23 5/8

19/7 * 5/2 = 95/14 = 6 11/14

17/5 * 7/3 = 119/15 = 7 14/15

24/11 * 4/3 = 32/33

Answer 2

To calculate the products of the given mixed numbers, we can convert them into improper fractions and then perform the multiplication. Here are the solutions:

1. 4 1/2 * 5 1/4: First, convert the mixed numbers to improper fractions: 4 1/2 = (4 * 2 + 1) / 2 = 9/2 5 1/4 = (5 * 4 + 1) / 4 = 21/4

   Multiply the improper fractions: (9/2) * (21/4) = (9 * 21) / (2 * 4) = 189/8

   The product of 4 1/2 and 5 1/4 is 189/8.

2. 2 5/7 * 2 1/2: Convert the mixed numbers to improper fractions: 2 5/7 = (2 * 7 + 5) / 7 = 19/7 2 1/2 = (2 * 2 + 1) / 2 = 5/2

   Multiply the improper fractions: (19/7) * (5/2) = (19 * 5) / (7 * 2) = 95/14

   The product of 2 5/7 and 2 1/2 is 95/14.

3. 3 2/5 * 2 1/3: Convert the mixed numbers to improper fractions: 3 2/5 = (3 * 5 + 2) / 5 = 17/5 2 1/3 = (2 * 3 + 1) / 3 = 7/3

   Multiply the improper fractions: (17/5) * (7/3) = (17 * 7) / (5 * 3) = 119/15

   The product of 3 2/5 and 2 1/3 is 119/15.

4. 2 2/11 * 1 1/3: Convert the mixed numbers to improper fractions: 2 2/11 = (2 * 11 + 2) / 11 = 24/11 1 1/3 = (1 * 3 + 1) / 3 = 4/3

   Multiply the improper fractions: (24/11) * (4/3) = (24 * 4) / (11 * 3) = 96/33

   The product of 2 2/11 and 1 1/3 is 96/33, which can be simplified to 32/11.
