Question

26 2/3 :(-2 2/3) =13:(0,1b)​

Answer 1

Ответ:

-13

Пошаговое объяснение:

26 2/3 : (-2 2/3) = 13 : (0,1в)

26 2/3 * 0,1в = -2 2/3 * 13

80/3 * 1/10в = -8/3 * 13

8/3 * 1/1в = -104/3

8/3в = -104/3

в = -104/3 : 8/3

в = -104/3 * 3/8

в = -104/8

в = -13

Answer 2

To solve the expression 26 2/3 : (-2 2/3) = 13 : (0,1b), let's break it down step by step.

First, let's convert the mixed numbers into improper fractions: 26 2/3 becomes (3 * 26 + 2) / 3 = 80/3 -2 2/3 becomes (3 * -2 + 2) / 3 = -4/3

Next, let's rewrite the expression: 80/3 : (-4/3) = 13 : (0,1b)

To divide fractions, we can multiply the first fraction by the reciprocal of the second fraction: (80/3) * (-3/4) = 13 : (0,1b)

Simplifying the multiplication on the left side: -240/12 = 13 : (0,1b)

Dividing by -20 on both sides: -240/12 ÷ -20 = 13 : (0,1b) ÷ -20

Simplifying the division on the left side: 20 = 13 : (0,1b) ÷ -20

To solve for (0,1b), we need to isolate it. Let's cross multiply: 20 * (0,1b) = 13 * -20

Simplifying the multiplication on the right side: 2b = -260

Finally, divide by 2 to solve for b: b = -260 / 2 b = -130

Therefore, the value of (0,1b) is -130.
