Answer 2

To solve this 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):

1. Calculate within the parentheses/brackets first: (35 - 1/4) * 5 + 20.8 / 8

2. Next, perform the subtraction inside the parentheses: 35 - 1/4 = 139/4

3. Now, you have the expression: (139/4) * 5 + 20.8 / 8

4. Continue with the multiplication and division from left to right: (139/4) * 5 = (139/4) * 5 = 139 * 5 / 4 = 695/4 20.8 / 8 = 2.6

5. Finally, add the results: 695/4 + 2.6

To add these fractions, you need a common denominator, which is 4. So, convert 2.6 to a fraction with a denominator of 4: 2.6 = 2.6 * 4/4 = 10.4/4

Now, add the fractions: (695/4) + (10.4/4) = (695 + 10.4) / 4 = 705.4 / 4

To simplify the fraction, divide both the numerator and denominator by their greatest common divisor, which is 0.4: (705.4 / 0.4) / (4 / 0.4) = 1763.5 / 10 = 176.35

So, the result of the expression is 176.35.
