Answer 1

Ответ:

Пошаговое объяснение:

( 8 7/12 - 2 8/16) / (-1.1) = -5 35/66

8 7/12 - 2 8/16 = 103/12 - 40/16 = (412-120) / 48 = 292/48 = 73/12

73/12 : (-1,1) = 73/12 : (-1 1/10) = 73/12 : (-11/10) = 73/12 * (-10/11) = -365/66 = -5 35/66

Answer 3

To simplify the given expression:

1. Convert mixed numbers to improper fractions:

   8 7/12 = (12 * 8 + 7)/12 = 103/12

   2 8/16 = (16 * 2 + 8)/16 = 40/16

2. Simplify the numerator:

   (103/12 - 40/16) = (103/12 - 40/16 * 3/3) = (103/12 - 120/48)

   To add or subtract fractions, you need to have a common denominator. Since 12 and 48 are both factors of 48, the common denominator is 48. Therefore:

   (103/12 - 120/48) = (103/12 * 4/4 - 120/48) = (412/48 - 120/48) = 292/48

3. Divide the numerator by the denominator:

   (292/48) / (-1.1) = (292/48) * (-10/11) = -(2920/528) = -55/99

Therefore, the simplified expression is -55/99.
