Answer 2

To calculate the expression, we need to convert the mixed numbers to improper fractions first. Here's the step-by-step calculation:

Step 1: Convert mixed numbers to improper fractions. 9 4/31 = (9 * 31 + 4) / 31 = 283/31 6 8/31 = (6 * 31 + 8) / 31 = 194/31 2 4/31 = (2 * 31 + 4) / 31 = 66/31

Step 2: Perform the subtraction inside the parentheses. 6 8/31 + 2 4/31 = (194/31) + (66/31) = (194 + 66) / 31 = 260/31

Step 3: Subtract the result from step 2 from 9 4/31. 9 4/31 - (6 8/31 + 2 4/31) = (283/31) - (260/31) = (283 - 260) / 31 = 23/31

Therefore, the result of the expression 9 4/31 - (6 8/31 + 2 4/31) is 23/31.
