Question

-2 1/2 * (-0,6) 3 1/3-8 -5 1/6 / 11/12

Answer 1

Пошаговое объяснение:

1)-5/2×0,6=1 1/2

2)3 1/3-8=-(8-3 1/3)=4 2/3

3)-31/6÷11/12=5 7/11

Answer 2

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

1. -2 1/2 * (-0.6): First, convert the mixed number -2 1/2 to an improper fraction: -2 1/2 = -5/2

Now, multiply -5/2 by -0.6: -5/2 * (-0.6) = 5/2 * 0.6 = 5/5 = 1

2. 3 1/3 - 8: Convert the mixed number 3 1/3 to an improper fraction: 3 1/3 = 10/3

Now, subtract 8 from 10/3: 10/3 - 8 = 10/3 - 24/3 = (10 - 24)/3 = -14/3

3. -5 1/6 / 11/12: Convert the mixed number -5 1/6 to an improper fraction: -5 1/6 = -31/6

Now, divide -31/6 by 11/12: (-31/6) / (11/12) = (-31/6) * (12/11) = -372/66

Next, simplify the fraction -372/66: -372/66 = -186/33 = -6

Now, let's put all the results together:

-2 1/2 * (-0.6) + 3 1/3 - 8 - 5 1/6 / 11/12

1 + (-14/3) - 6

Now, let's find a common denominator to combine the fractions:

Common denominator for 1 and -14/3 is 3: 1 = 3/3

Now, we have:

3/3 + (-14/3) - 6

Combine the fractions:

(3 - 14)/3 - 6

-11/3 - 6

Now, let's find a common denominator to combine the fractions:

Common denominator for -11/3 and 6 is 3: -11/3 = -11/3

Now, we have:

(-11 - 18)/3

Combine the fractions:

-29/3

So, the final result is -29/3.
