Answer 2

Calculating the Expression

To solve the given expression, we'll follow the order of operations (PEMDAS/BODMAS) which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division, and Addition and Subtraction.

The given expression is: (6.87 - 2.67) : 0.07 + 0.3 * 2.9 = (6.42 - 2.62) * 0.6 + 2.8 : 0.04

Let's solve it step by step.

1. Calculate (6.87 - 2.67) : 0.07 2. Calculate 0.3 * 2.9 3. Calculate (6.42 - 2.62) * 0.6 4. Calculate 2.8 : 0.04

Step 1: Calculate (6.87 - 2.67) : 0.07

The result of (6.87 - 2.67) is 4.2. Then, 4.2 divided by 0.07 is 60.

Step 2: Calculate 0.3 * 2.9

The result of 0.3 multiplied by 2.9 is 0.87.

Step 3: Calculate (6.42 - 2.62) * 0.6

The result of (6.42 - 2.62) is 3.8. Then, 3.8 multiplied by 0.6 is 2.28.

Step 4: Calculate 2.8 : 0.04

The result of 2.8 divided by 0.04 is 70.

Final Result

So, the final result of the given expression is: 60 + 0.87 = 2.28 + 70 60.87 = 72.28

Therefore, the solution to the given expression is 60.87 = 72.28.
