Question

4) (-4 2/3):2/9 (- 6 1/4 ) : (-5/8)​

Answer 1

Ответ:

Пошаговое объяснение:

-4 2/3 : 2/9 = -14/3 * 9/2 = -7/1 * 3/1 = -21

-6 1/4 : (-5/8) = -25/4 * (-8/5) = 5/1 * 2/1 = 10

Answer 2

To solve the expression (-4 2/3) : (2/9) (-6 1/4) : (-5/8), we need to perform the operations in order.

First, let's simplify the fractions within the expression: (-4 2/3) = -4 - (2/3) = -4 - (2/3) = -4 * (3/3) - (2/3) = -12/3 - 2/3 = -14/3

(-6 1/4) = -6 - (1/4) = -6 - (1/4) = -6 * (4/4) - (1/4) = -24/4 - 1/4 = -25/4

Now we can rewrite the expression as: (-14/3) : (2/9) * (-25/4) : (-5/8)

To divide fractions, we multiply by the reciprocal of the second fraction. So, let's proceed with the division first: (-14/3) : (2/9) = (-14/3) * (9/2) = (-14 * 9) / (3 * 2) = -126/6 = -21

Next, we can solve the division in the second part of the expression: (-25/4) : (-5/8) = (-25/4) * (-8/5) = (25 * 8) / (4 * 5) = 200/20 = 10

Finally, we have: (-21) * (10) = -210

Therefore, the value of the expression (-4 2/3) : (2/9) (-6 1/4) : (-5/8) is -210.
