Answer 3

To solve the expression, follow the order of operations (PEMDAS: Parentheses, Exponents, Multiplication, and Division from left to right, Addition, and Subtraction from left to right):

Step 1: Perform the division from left to right: 70 / 20 = 3.5 1 / 2 = 0.5 49 / 12 ≈ 4.0833 (rounded to four decimal places)

The expression now becomes: 3.5 + 0.5 + 4.0833 : 1 1/6

Step 2: Convert the mixed number 1 1/6 to an improper fraction: 1 1/6 = (6 * 1 + 1) / 6 = 7/6

The expression now becomes: 3.5 + 0.5 + 4.0833 : 7/6

Step 3: Perform the remaining division: 4.0833 / (7/6) = 4.0833 * (6/7) ≈ 3.4732 (rounded to four decimal places)

The final expression is: 3.5 + 0.5 + 3.4732

Step 4: Perform the addition: 3.5 + 0.5 + 3.4732 ≈ 7.4732 (rounded to four decimal places)

So, the result of the expression is approximately 7.4732.
