Answer 2

To solve the expression, follow the order of operations (PEMDAS/BODMAS):

1. Perform operations inside parentheses first.
2. Next, perform any division or multiplication from left to right.
3. Finally, perform any addition or subtraction from left to right.

Let's solve step by step:

Step 1: Operations inside parentheses 2,4 - 0,82 ÷ 0,4

Step 2: Division 0,82 ÷ 0,4 = 2.05

Step 3: Subtraction 2.4 - 2.05 = 0.35

Now, we have: 2/3 + 2 * 0.35

Step 4: Multiplication 2 * 0.35 = 0.7

Step 5: Addition 2/3 + 0.7

To add fractions, find a common denominator. The common denominator here is 3.

Step 6: Convert 0.7 to a fraction with a denominator of 3. 0.7 = 7/10 To get the denominator of 3, multiply both the numerator and denominator by 3/10. 7/10 * 3/3 = 21/30

Step 7: Add the fractions. 2/3 + 21/30

Step 8: Find a common denominator for the fractions (3 * 10 = 30) and add them. (2 * 10 + 21) / 30 = 41/30

So, the final result is 41/30 or approximately 1.3667.
