Answer 2

To perform the arithmetic operation, we need to simplify the expression step by step. Let's start:

Step 1: Simplify the expression inside the parentheses. 15/9 - 1/6 = (15/9 - 2/12) Now, both fractions have the same denominator, so we can combine them: (15/9 - 2/12) = (15/9 - 1/6) = (5/3 - 1/6)

Step 2: Find the common denominator for (5/3 - 1/6). The common denominator is 6, so we need to convert both fractions to have a denominator of 6: (5/3) * (2/2) = 10/6 (1/6)

Step 3: Subtract the fractions. (10/6 - 1/6) = 9/6 = 3/2

Step 4: Now, we have 2 1/12. Convert it to an improper fraction. 2 1/12 = (2 * 12 + 1) / 12 = 25/12

Step 5: Finally, perform the subtraction. 25/12 - 3/2

To subtract fractions, we need a common denominator, which is 12 in this case. (25/12) - (3/2) = (25/12) - (18/12)

Now, we can subtract them: (25/12) - (18/12) = 7/12

So, the result of the expression is 7/12.
