Question

(1 1/9-5 1/3):(-1/5+2,1)

Answer 1

(1 1/9 - 5 1/3) : (-1/5 + 2,1) = -2 2/9

1) 1 1/9 - 5 1/3 = 10/9 - 16/3 = 30/27 - 144/27 = -114/27 = -4 2/9

2) -1/5 + 2,1 = -0,2 + 2,1 = 1,9

3) -4 2/9 : 1,9 = -38/9 : 19/10 = -38/9 * 10/19 = -20/9 = -2 2/9

Ответ: -2 2/9

Answer 2

It looks like you've provided a mathematical expression involving fractions and coordinates. Let's break it down step by step:

Expression: (1 1/9 - 5 1/3) : (-1/5 + 2,1)

Step 1: Convert mixed numbers to improper fractions 1 1/9 = (9 + 1) / 9 = 10/9 5 1/3 = (15 + 1) / 3 = 16/3

Step 2: Perform subtraction 10/9 - 16/3

To subtract fractions with different denominators, we need a common denominator. The least common multiple of 9 and 3 is 9.

10/9 = (10/9) * (3/3) = 30/27 16/3 = (16/3) * (9/9) = 144/27

Now the subtraction becomes: (30/27) - (144/27) = -114/27

Step 3: Simplify the result -114/27 can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 9.

-114/27 = (-114 ÷ 9) / (27 ÷ 9) = -12/3 = -4

So, the result of the expression (1 1/9 - 5 1/3) is -4.

However, the expression also contains a part with coordinates: (-1/5 + 2,1)

Step 4: Perform addition of coordinates -1/5 + 2 = (2 * 5 - 1) / 5 = 9/5

So, the coordinates become: (9/5, 1)

In summary, the given expression evaluates to: Result: -4 Coordinates: (9/5, 1)
