Answer 2

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

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's solve the expression step-by-step:

1. Convert the decimal separators to match your local convention. In this case, replace commas with dots: 120:0.05 - (15.7:0.2) * 10.1

2. Perform the division inside the parentheses first: 120:0.05 - (15.7 ÷ 0.2) * 10.1

3. Calculate the division inside the parentheses: 120:0.05 - 78.5 * 10.1

4. Perform the multiplication: 120:0.05 - 792.85

5. Finally, calculate the division: 2400 - 792.85

6. Perform the subtraction: 1607.15

The result of the expression is 1607.15.
