Answer 2

To solve this expression, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right). Let's break down the expression step by step:

1. First, let's deal with the divisions and multiplications from left to right:

   1,24 ÷ 3,1 + 12 ÷ 0,25 – 2 ÷ 25 + 18 ÷ 0,45

2. Now, calculate the results of each division and multiplication:

   0,4 + 48 - 0,08 + 40

3. Next, perform the addition and subtraction operations from left to right:

   0,4 + 48 = 48,4 48,4 - 0,08 = 48,32 48,32 + 40 = 88,32

So, the result of the expression is 88.32.
