Answer 3

To solve this mathematical expression, follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right):

Given expression: 0.9 * (70.5 - 67.2 / 4.2) + 13.6

1. First, perform the division inside the parentheses: 67.2 / 4.2 = 16.
2. Then, subtract the result from 70.5: 70.5 - 16 = 54.5.
3. Now, multiply the result by 0.9: 0.9 * 54.5 = 49.05.
4. Finally, add 13.6 to the previous result: 49.05 + 13.6 = 62.65.

So, the result of the expression is 62.65.
