Answer 1

Ответ точно правильный

Answer 2

To solve this expression, let's first perform the operations step by step:

Step 1: Simplify the expression inside the parentheses. 2 1/3 - 1 2/3 • 0.75

To make it easier to calculate, let's convert the mixed numbers to improper fractions: 2 1/3 = (32 + 1) / 3 = 7/3 1 2/3 = (31 + 2) / 3 = 5/3

Now, we have: (7/3 - 5/3) • 0.75 (2/3) • 0.75

Step 2: Perform the multiplication inside the parentheses. (2/3) • 0.75 = 2/3 * 0.75 = 1.5/3 = 0.5

Step 3: Perform the division outside the parentheses. Now, we have the expression: (0.5) ÷ 4 1/3 - 0.125

To make it easier to calculate, let's convert the mixed number to an improper fraction: 4 1/3 = (3*4 + 1) / 3 = 13/3

Now, we have: (0.5) ÷ (13/3) - 0.125

Step 4: Perform the division. (0.5) ÷ (13/3) = 0.5 * (3/13) = 1.5/13 ≈ 0.11538461538 (rounded to 11 decimal places)

Step 5: Perform the final subtraction. 0.11538461538 - 0.125 ≈ -0.00961538462 (rounded to 11 decimal places)

So, the final result of the expression is approximately -0.00961538462.
