Ответ: 8,05

6)

23,733-22-0,9=0,833

4998÷0,833=6000

98,72+1,28=100

6000×0,151=906

906÷100=9,06

Answer 3

Let's solve each of these mathematical expressions step by step:

1. $6,067 + 3,933 - 6,3 \div 0,3 \cdot 0,304 + 0,394$

   First, let's perform the division and multiplication: $6,067 + 3,933 - 21 \cdot 0,304 + 0,394$

   Now, do the multiplications: $6,067 + 3,933 - 6.384 + 0,394$

   Finally, add and subtract: $10,000 - 6.384 + 0,394$

   $10,000 - 5.990 = 4.010$

2. $109,07 - 18,814 \div 0,2 - 9,971 + 0,62 - 0,17 \cdot 3,7$

   First, perform the division and multiplication: $109,07 - 94.07 - 9,971 + 0,62 - 0,629$

   Now, do the additions and subtractions: $109,07 - 94.07 - 9.971 + 0,62 - 0,629 = 5.0$

3. $1,96 \cdot 10 - 61,44 \div 6,4 - 32,765 \cdot 0,2 + 2,583$

   First, perform the multiplication and division: $19.6 - 9.6 - 6.4 - 6.553 + 2.583$

   Now, do the additions and subtractions: $19.6 - 9.6 - 6.4 - 6.553 + 2.583 = -0.453$

4. $0,264 \cdot (93,96 + 185,81 - 15,77) \div 0,99 \cdot 0,1$

   First, calculate the expression inside the parentheses: $0,264 \cdot (264.0) \div 0,99 \cdot 0,1$

   Now, do the multiplication and division: $69.696 \div 0.99 \cdot 0.1$

   $70.303 \cdot 0.1 = 7.03$

5. $2,587 + 16,826 \div 2 - 0,059 \div (0,79 - 0,69) \cdot 5$

   First, calculate the expression inside the parentheses: $2,587 + 8.413 - 0.059 \div 0.1 \cdot 5$

   Now, do the division and multiplication: $2.587 + 8.413 - 0.59 \cdot 5$

   Now, perform the multiplication: $2.587 + 8.413 - 2.95$

   Finally, add and subtract: $10.0 - 2.95 = 7.05$

6. $4998 \div (23.733 - 22 - 0.9) \cdot 0.151 \div (98.72 + 1.28)$

   First, calculate the expression inside the parentheses: $4998 \div (0.033 - 0.9) \cdot 0.151 \div (100.0 + 1.28)$

   Now, do the division and multiplication: $4998 \div (-0.867) \cdot 0.151 \div 101.28$

   Now, perform the division and multiplication: $-5757.49 \cdot 0.151 \div 101.28$

   Finally, do the multiplication and division: $-869.39 \div 101.28 ≈ -8.58$

7. $0.54 + 35.51 \div 67 + (3000.8 - 0.8) \cdot (0.613 - 0.61)$

   First, perform the subtraction inside the parentheses: $0.54 + 35.51 \div 67 + 3000.0 \cdot 0.003$

   Now, do the division and multiplication: $0.54 + 0.53 + 9.0$

   Finally, add: $0.54 + 0.53 + 9.0 = 10.07$

8. $81.08 - (95.278 + 434.44 \cdot 0.05) \cdot 0.014 \div 0.6 \div 0.039$

   First, perform the multiplication inside the parentheses: $81.08 - (95.278 + 21.722) \cdot 0.014 \div 0.6 \div 0.039$

   Now, do the addition: $81.08 - 117.0 \cdot 0.014 \div 0.6 \div 0.039$

   Next, perform the multiplication and division: $81.08 - 1.638 \div 0.6 \div 0.039$

   Continue with the division: $81.08 - 2.73 \div 0.039$

   Finally, do the division:
