Answer 3

To solve the expression 17.8 - 37 ÷ 2 + 3/17 + 1 2/7, we follow the order of operations (PEMDAS/BODMAS). Here's the step-by-step solution:

Step 1: Divide 37 by 2 37 ÷ 2 = 18.5

Step 2: Convert mixed numbers to improper fractions 3/17 + 1 2/7 = 3/17 + (7/7 * 1) + 2/7 = 3/17 + 7/7 + 2/7 = 3/17 + 7/7 + 2/7 = 3/17 + 7/7 + 2/7 = (3 + 7 + 2)/7 = 12/7

Step 3: Perform addition and subtraction from left to right 17.8 - 18.5 + 12/7

Step 4: Subtract 18.5 from 17.8 17.8 - 18.5 = -0.7

Step 5: Add -0.7 and 12/7 -0.7 + 12/7 = (7 * -0.7 + 12)/7 = (-4.9 + 12)/7 = 7.1/7 = 1.0142857 (rounded to seven decimal places)

Therefore, the result of the expression 17.8 - 37 ÷ 2 + 3/17 + 1 2/7 is approximately 1.0142857.
