Answer 2

Let's break down the expression step by step:

1. 4.27 + 2.15 - 1.245 ÷ 5 = 4.27 + 2.15 - 0.249 (dividing 1.245 by 5) = 4.27 + 2.15 - 0.249 = 6.42 - 0.249 = 6.170751

2. 8.5 - 4.5 ÷ 2 + 0.75(3.248 ÷ 4) - 0.093 * 0.08 = 8.5 - 2.25 + 0.75(0.812) - 0.00744 (dividing 4.5 by 2 and multiplying 0.75 and 0.08) = 8.5 - 2.25 + 0.609 - 0.00744 = 6.25 + 0.609 - 0.00744 = 6.85156 - 0.00744 = 6.84412

3. 0.9 + 0.2746 ÷ 8 - 2.59 ÷ 5 - 0.5 ÷ 2 = 0.9 + 0.034325 - 0.518 - 0.25 (dividing 0.2746 by 8 and dividing 2.59 by 5) = 0.9 + 0.034325 - 0.518 - 0.25 = 0.784325 - 0.518 - 0.25 = 0.266325 - 0.25 = 0.016325

So, the result of the expression is approximately 6.170751 + 6.84412 + 0.016325, which is approximately 13.031196.
