Question

( 6 - 9 3/5 ) × (- 1 2/3) - 12 ÷ ( - 3/4 + 1/8 )

Answer 1

Ответ:

Пошаговое объяснение:

6 - 9 3/5= -3 3\5

-3 3\5*(-1 2\3)= -18\5*(-5\3)=6

- 3/4 + 1/8=-6\8+1\8= -5\8

12:(-5\8)=12*(-8\5)= -19.2

6-(-19.2)=6+19.2=25.2

Answer 2

Let's break down the expression step by step:

1. Calculate the first term:
   $6 - 9 \frac{3}{5} = \frac{30}{5} - \frac{48}{5} + \frac{3}{5} = \frac{-15}{5} = -3$.

2. Calculate the second term:
   $-1 \frac{2}{3} = -\frac{5}{3}$.

3. Calculate the third term within the parentheses:
   $-3/4 + 1/8 = -\frac{6}{8} + \frac{1}{8} = -\frac{5}{8}$.

4. Calculate the fourth term:
   $12 \div (-\frac{5}{8}) = 12 \cdot (-\frac{8}{5}) = -\frac{96}{5}$.

5. Substitute the results into the first expression:
   $-3 \cdot (-\frac{5}{3}) - \frac{96}{5} = \frac{15}{3} - \frac{96}{5} = 5 - \frac{96}{5} = \frac{25 - 96}{5} = \frac{-71}{5}$.

So, the value of the given expression is $-\frac{71}{5}$.
