1 8/27:(-1 5/9)=5/6 решение

Answer 1

1 8/27=35/27.
-1 5/9= -14/9.
35/27:(-14/9)=35/27*(-9/14)= -5/6.
Ответ: -5/6.
У тебя ошибка в условии: плюс разделить на минус будет минус.

Answer 2

To solve the equation 1 ÷ 8/27 = (-1 5/9) ÷ 5/6, we need to simplify both sides and convert any mixed numbers into improper fractions.

Let's start with the left side of the equation:

1 ÷ 8/27

To divide by a fraction, we can multiply by its reciprocal:

1 ÷ 8/27 = 1 × 27/8

Now, let's simplify the fraction on the left side:

1 × 27/8 = 27/8

Now, let's simplify the right side of the equation:

(-1 5/9) ÷ 5/6

First, convert the mixed number to an improper fraction:

-1 5/9 = -9/9 + 5/9 = -14/9

Now, divide the fractions:

-14/9 ÷ 5/6 = -14/9 × 6/5

Multiply the numerators and denominators:

-14 × 6 / 9 × 5 = -84/45

The equation becomes:

27/8 = -84/45

To further solve this equation, we can cross-multiply:

27 × 45 = -84 × 8

1215 = -672

However, the equation 1215 = -672 is not true, which means there is no solution to the equation.

Therefore, the equation 1 ÷ 8/27 = (-1 5/9) ÷ 5/6 does not have a solution.
