Answer 1

Відповідь: (4 5/9-3 7/12):(-1 8/7)= -49/108

Answer 2

Ответ:

-49/108

Пошаговое объяснение:

1) 4 5/9 - 3 7/12 = 4 20/36 - 3 21/36 = 3 56/36 - 3 21/36 = 35/36

2) 35/36 : (-1 8/7) = 35/36 : (-15/7) = 35/36 * (-7/15) = 7/36 * (-7/3) = -49/108

Answer 3

To calculate the expression (4 5/9 - 3 7/12) / (-1 8/7), you can follow these steps:

Step 1: Convert mixed numbers to improper fractions.

• 4 5/9 as an improper fraction is (4 * 9 + 5) / 9 = 41/9.
• 3 7/12 as an improper fraction is (3 * 12 + 7) / 12 = 43/12.
• -1 8/7 as an improper fraction is (-1 * 7 + 8) / 7 = 1/7.

Step 2: Perform the subtraction. (41/9 - 43/12)

Step 3: Find a common denominator for the fractions, which is 36 in this case. To make both fractions have a denominator of 36, we can multiply the first fraction by 4/4 and the second fraction by 3/3:

(41/9 * 4/4 - 43/12 * 3/3) (164/36 - 129/36)

Step 4: Subtract the fractions with the common denominator. (164/36 - 129/36) = (164 - 129) / 36 = 35/36.

Step 5: Divide the result by the third fraction. (35/36) / (1/7)

Step 6: Invert and multiply by the reciprocal of the third fraction. (35/36) * (7/1) = (35 * 7) / (36 * 1) = 245/36.

So, the final result of the expression is 245/36.
