Question

0,75a-b: 8 1/11 a=111/3 b=8,9 ?​

Answer 1

Ответ:

26,65

Пошаговое объяснение:

a = 111/3 b = 8,9

0,75a - b : 8 1/11 = 75/100 * 111/3 - 89/10 : 89/11 = 3/4 * 111/3 - 89/10 * 11/89 =

111/4 - 11/10 = 27,75 - 1,1 = 26,65

Answer 2

To evaluate the expression "0.75a - b" when a = 111/3 and b = 8.9, we simply need to substitute these values into the expression and perform the calculations.

Given: a = 111/3 = 37 b = 8.9

Now, let's evaluate the expression "0.75a - b":

0.75 * a = 0.75 * 37 = 27.75

Subtracting b:

27.75 - 8.9 ≈ 18.85

So, when a = 111/3 and b = 8.9, the value of "0.75a - b" is approximately 18.85.
