Answer 1

Ответ:

12/5 или 2.4

Пошаговое объяснение:

(2/5-6,6)÷(-5/4-4/3)

(2/5 - 33/5) : ( -31/12)

-31/5 : (-31/12)

31/5 * 12/31

1/5 * 12/31

1/5 * 12

12/5 или 2.4

Answer 2

Ответ:

Пошаговое объяснение:

2/5-6.6=0.4-6.6=-6.2

5/4-4/3=15/12-16/12=-1/12

-6.2:(-1/12)=-31/5*(-12)=372/5=74.4

Answer 3

To solve the expression (2/5 - 6,6) ÷ (-5/4 - 4/3), let's first simplify the expression inside the parenthesis:

(2/5 - 6,6) = (2/5 - 6 + 0.6) = (2/5 - 5.4)

Now, find the common denominator between 5 and 10 (since 5 and 4 share no common factors):

Common denominator: 5 * 4 = 20

Now, rewrite the fractions with the common denominator:

(2/5 - 5.4) = (2/5 * 4/4 - 5.4 * 4/4) = (8/20 - 21.6/20)

Now, we can combine the fractions:

(8/20 - 21.6/20) = (-13.6/20)

Next, we simplify the expression by dividing by -5/4 - 4/3:

(-13.6/20) ÷ (-5/4 - 4/3)

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

(-13.6/20) * (-3/4 - 4/3)

Now, find the common denominator between 4 and 3 (since -4 and -3 share no common factors):

Common denominator: 4 * 3 = 12

Now, rewrite the fractions with the common denominator:

(-13.6/20) * (-3/4 * 3/3 - 4/3 * 4/4)

Now, we can combine the fractions:

(-13.6/20) * (-9/12 + 16/12) = (-13.6/20) * (7/12)

Next, multiply the fractions:

-13.6 * 7 / (20 * 12) = -95.2 / 240 = -119/300

So, the simplified result of the expression is -119/300.
