Answer 2

To solve the expression, let's break it down step by step using the order of operations (also known as PEMDAS):

1. Start by evaluating the parentheses: (1.1/4 + 1/12)

   • 1.1/4 = 0.275
   • 1/12 = 0.0833 (rounded to four decimal places)
   • Adding them together: 0.275 + 0.0833 = 0.3583 (rounded to four decimal places)

2. Next, multiply the result from step 1 by 5: 0.3583 * 5 = 1.7915 (rounded to four decimal places)

3. Now, perform the division: 7 - 14 / 1.7915

   • 14 / 1.7915 ≈ 7.8054 (rounded to four decimal places)
   • Subtracting from 7: 7 - 7.8054 ≈ -0.8054 (rounded to four decimal places)

4. Finally, divide the result from step 3 by 3: -0.8054 / 3 ≈ -0.2685 (rounded to four decimal places)

Therefore, the result of the expression 7-14/5*(1.1/4+1/12):3 is approximately -0.2685.
