Answer 2

To solve the expression (12-8.4):0.09•0.7-0.3•(0.6+3.12):(14.18-7.98):0.01, we can follow the order of operations (also known as PEMDAS or BIDMAS) to simplify the expression step by step:

Step 1: Simplify the parentheses (0.6+3.12) = 3.72

Step 2: Perform multiplication and division from left to right (12-8.4):0.09•0.7 = 3.6:0.09•0.7 = 40•0.7 = 28

Step 3: Simplify the parentheses (14.18-7.98) = 6.2

Step 4: Perform division from left to right 28:(14.18-7.98) = 28:6.2 = 4.516129032258064

Step 5: Perform multiplication and subtraction from left to right 0.3•3.72 = 1.116 4.516129032258064 - 1.116 = 3.4

So the final answer is 3.4.
