Answer 3

To solve this mathematical expression, let's 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)

Here's the calculation step by step:

1. 2.66 : 3.8 = 0.700 (approximately)
2. 0.81 • 0.12 = 0.0972
3. Multiplying 0.0972 by 0.12 = 0.011664
4. Adding 0.011664 and 0.0372 = 0.048864

So, the final result of the expression 2.66 : 3.8 - 0.81 • 0.12 + 0.0372 is approximately:

0.700 - 0.048864 + 0.0372 = 0.688335
