Question

-2 1/25 + 0,3 : (0,8 * 6,75 - 6,25) =

Answer 1

-2 1/25 + 0,3 : (0,8•6,75-6,25)= - 51/25+3/10:(5,4-6,25)=- 51/25 +3/10:(-0,85)=- 51/25 + 3/10 :(-17/20)=-51/25-3/10•20/17=-51/25 -3•2/17=-51/25-6/17=- 1017/425= -2 167/425

Answer 2

To simplify the expression, follow the order of operations: parentheses, multiplication/division (from left to right), and addition/subtraction (from left to right).

Step 1: Evaluate the expression inside the parentheses first: 0.8 * 6.75 - 6.25 = 5.4 - 6.25 = -0.85

Step 2: Now, the expression becomes: 0.3 : (-0.85)

Step 3: Division of 0.3 by -0.85: 0.3 / -0.85 ≈ -0.3529 (rounded to four decimal places)

Step 4: Add the fractions: -2 + 1/25 = -2 + 0.04 = -1.96

Step 5: Finally, combine the results: -1.96 - 0.3529 ≈ -2.3129 (rounded to four decimal places)

Therefore, the result is approximately -2.3129.
