Question

(2 3/8 - 1 5/6) : (-1 5/8) =

Answer 1

Ответ:

- 1/3

Пошаговое объяснение:

(2 3/8 - 1 5/6) : (-1 5/8) = (19/8 - 11/6) : (-13/8) = (57/24 - 44/24) : (-13/8) = (57-44)/24 : (-13/8) = 13/24 : (-13/8) = - (13*8)/(24*13) = - 1/3

Answer 2

To solve the expression (2 3/8 - 1 5/6) : (-1 5/8), let's break it down step by step.

First, let's convert the mixed numbers into improper fractions: 2 3/8 = (2 * 8 + 3) / 8 = 19/8 1 5/6 = (1 * 6 + 5) / 6 = 11/6 -1 5/8 = (-1 * 8 + 5) / 8 = -3/8

Now, let's perform the subtraction: (19/8 - 11/6) : (-3/8)

To simplify the expression further, we need to find a common denominator for all the fractions involved. The common denominator for 8 and 6 is 24.

(19/8 * 3/3 - 11/6 * 4/4) : (-3/8)

Now we have: (57/24 - 44/24) : (-3/8)

Subtract the numerators: (13/24) : (-3/8)

To divide fractions, we can multiply the first fraction by the reciprocal of the second fraction: (13/24) * (-8/3)

Multiply the numerators and denominators: (-104/72) or simplified, (-13/9)

Therefore, (2 3/8 - 1 5/6) : (-1 5/8) is equal to -13/9.
