Answer 3

To evaluate the expression (3.6 × 5/12 - 4 1/6) ÷ (-16.2 - 2 1/9 + 15.2), let's break it down step by step:

Step 1: Simplify the numerator. 3.6 × 5/12 = 1.5

Step 2: Convert the mixed number in the numerator to an improper fraction. 4 1/6 = 4 + 1/6 = 24/6 + 1/6 = 25/6

Step 3: Simplify the denominator. -16.2 - 2 1/9 + 15.2 = -16.2 - (2 + 1/9) + 15.2 = -16.2 - 18/9 - 1/9 + 15.2 = -16.2 - 19/9 + 15.2 = -16.2 - (19 + 1/9) + 15.2 = -16.2 - 20/9 + 15.2 = -146/9 + 137/9 = -9/9 = -1

Step 4: Substitute the simplified numerator and denominator back into the expression. (1.5 - 25/6) ÷ (-1)

Step 5: Simplify the expression further. 1.5 - 25/6 = 9/6 - 25/6 = -16/6 = -8/3

Now we have the expression (-8/3) ÷ (-1).

Step 6: Divide the numerator by the denominator. (-8/3) ÷ (-1) = (-8/3) × (-1/1) = 8/3

Therefore, the value of the expression (3.6 × 5/12 - 4 1/6) ÷ (-16.2 - 2 1/9 + 15.2) is 8/3 or approximately 2.67.
