Answer 2

To solve the expression, let's break it down step by step:

Step 1: Simplify the expression within parentheses. (-0.3) = -0.3

Step 2: Multiply 5/6 by -0.3 (5/6) × (-0.3) = -0.25

Step 3: Simplify the expression within the division. (4/5) ÷ (1 целую 1/15)

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction.

1 целую 1/15 can be converted to an improper fraction: 1 целую 1/15 = (1 × 15 + 1)/15 = 16/15

Now we can divide:

(4/5) ÷ (16/15)

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction:

(4/5) × (15/16)

Step 4: Multiply the fractions:

(4 × 15) / (5 × 16) = 60/80

Step 5: Simplify the fraction:

60/80 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 20:

60/80 = (60 ÷ 20) / (80 ÷ 20) = 3/4

Step 6: Subtract the result from step 2 from the result in step 5:

-0.25 - 3/4

To subtract fractions, we need a common denominator. The common denominator here is 4:

-0.25 = -0.25 × 4/4 = -1/4

Now we can subtract:

-1/4 - 3/4 = (-1 - 3)/4 = -4/4 = -1

Therefore, the final result is -1.
