Answer 1

Ответ:

Пошаговое объяснение:

-5 1/8+1 1/8=-4

-5/6-3/14=-35/42-9/42=-1 2/21

-4*(-1 2/21)=-4*(-21/23)=-84/23=-3 15/23

Answer 2

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

(-5 1/8 + 1 1/8) can be simplified as follows: -5 1/8 can be written as -41/8. 1 1/8 can be written as 9/8. Therefore, (-5 1/8 + 1 1/8) becomes (-41/8 + 9/8).

Next, (-5/6 - 3/14) can be simplified as follows: To combine these fractions, we need to find a common denominator, which is 42. -5/6 can be written as -35/42. -3/14 can be written as -9/42. Therefore, (-5/6 - 3/14) becomes (-35/42 - 9/42).

Now, let's multiply the two expressions together: ((-41/8 + 9/8) * (-35/42 - 9/42))

First, we'll simplify the expression inside the parentheses: (-41/8 + 9/8) can be combined to give -32/8, which simplifies to -4.

(-35/42 - 9/42) can be combined to give -44/42, which simplifies to -22/21.

Finally, we multiply the simplified expressions: -4 * (-22/21).

Multiplying the two fractions together, we get: (-4) * (-22/21) = 88/21.

Therefore, the final result of the expression (-5 1/8 + 1 1/8) * (-5/6 - 3/14) is 88/21.
