Answer 1

Ответ:

Пошаговое объяснение:

А)

11/8 * 32 = 11/1 * 4 = 44/1 = 44

Б)

8/51 * 17/20 = 2/3 * 1/5 = 2/15

В)

1. 7/18 * 1. 1/8 = 25/18 * 9/8 = 25/2 * 1/8 = 25/16 =

1. 9/16

Answer 2

а) 11/8 * 32 = 44 б) 8/51 * 17/20 = 0.05294117647 в) 1 целая 7/18 * 1 целая 1/8 = 1 целая 1/36

Calculation Details:

a) To multiply fractions, you multiply the numerators together and the denominators together. So, for 11/8 * 32, you would multiply 11 * 32 to get the numerator and 8 * 1 to get the denominator. This gives you 352/8, which simplifies to 44.

b) To multiply fractions, you multiply the numerators together and the denominators together. So, for 8/51 * 17/20, you would multiply 8 * 17 to get the numerator and 51 * 20 to get the denominator. This gives you 136/1020, which simplifies to 0.13333333333. Rounded to 11 decimal places, it is approximately 0.05294117647.

в) To multiply mixed numbers, you first convert them to improper fractions. For 1 целая 7/18, you multiply the whole number (1) by the denominator (18) and add the numerator (7) to get the new numerator. The denominator remains the same. So, 1 целая 7/18 becomes 25/18. Similarly, 1 целая 1/8 becomes 9/8. Then, you multiply the numerators together and the denominators together. So, for 25/18 * 9/8, you would multiply 25 * 9 to get the numerator and 18 * 8 to get the denominator. This gives you 225/144, which simplifies to 1 целая 1/36.

Therefore, the results are: а) 11/8 * 32 = 44 б) 8/51 * 17/20 = 0.05294117647 в) 1 целая 7/18 * 1 целая 1/8 = 1 целая 1/36
