Question

2 1/6+2 1/12*(0,82:0,4-2,75)*1,2

Answer 1

1. 0,82:0,4-2,75=-0,7
2. 2 1/6+2 1/12=0,5
3. 0,5*(-0,7)*1,2=-0,42

Answer 2

Let's break down the expression step by step:

1. $2 \frac{1}{6}$ can be converted to an improper fraction:
   $2 \frac{1}{6} = \frac{2 \times 6 + 1}{6} = \frac{13}{6}$

2. $2 \frac{1}{12}$ can be converted to an improper fraction:
   $2 \frac{1}{12} = \frac{2 \times 12 + 1}{12} = \frac{25}{12}$

3. Now, let's calculate $0.82 \div 0.4 - 2.75$:
   $0.82 \div 0.4 - 2.75 = 2.05 - 2.75 = -0.7$

4. Multiply the result from step 3 by 1.2:
   $-0.7 \times 1.2 = -0.84$

5. Finally, multiply the result from step 4 by $\frac{25}{12}$:
   $-0.84 \times \frac{25}{12} = -1.75$

Now, add $\frac{13}{6}$ to $-1.75$:

$\frac{13}{6} - 1.75$

To add fractions, find a common denominator. In this case, the common denominator is 6:

$\frac{13}{6} = \frac{13 \times 1}{6 \times 1} = \frac{13}{6}$

So, the expression $2 \frac{1}{6} + 2 \frac{1}{12} \times (0.82 \div 0.4 - 2.75) \times 1.2$ evaluates to $\frac{13}{6} - 1.75$.
