Answer 2

Ответ:

Пошаговое объяснение:

4/7 = 0.57

-5.5/6 = -0.9

-5/62 = -0.08

-4.3/7= -0.6

0.57*(-0.9)*(-0.08)*(-0.6)=-0.024

Answer 3

To solve the expression 4/7 × (-5 5/6) - 5/62 × (-4 3/7), let's break it down step by step:

First, let's simplify the mixed numbers (-5 5/6) and (-4 3/7):

-5 5/6 = -5 + 5/6 = -30/6 + 5/6 = -25/6

-4 3/7 = -4 + 3/7 = -28/7 + 3/7 = -25/7

Now, we can substitute the simplified mixed numbers into the expression:

4/7 × (-25/6) - 5/62 × (-25/7)

Next, let's multiply the fractions:

(4/7) × (-25/6) = -100/42

(5/62) × (-25/7) = -125/434

Finally, let's subtract the two results:

-100/42 - (-125/434)

To subtract fractions, we need a common denominator. The least common multiple (LCM) of 42 and 434 is 6,006.

-100/42 = -2,500/6,006

-125/434 = -750/6,006

Now we can subtract:

-2,500/6,006 - (-750/6,006) = -2,500/6,006 + 750/6,006 = -1,750/6,006

So, the simplified result of the expression 4/7 × (-5 5/6) - 5/62 × (-4 3/7) is -1,750/6,006.
