Answer 1

9 4/31-(6 8/31+2 4/31)=9 4/31-8 12/31=23/31

Answer 2

To perform the arithmetic calculation, first, you need to convert all the fractions into a common denominator. In this case, the common denominator is 31. Then, you can perform the subtraction and addition. Let's proceed step by step:

Step 1: Convert mixed numbers to improper fractions:

• 9 4/31 = (9 * 31 + 4)/31 = 289/31
• 6 8/31 = (6 * 31 + 8)/31 = 194/31
• 2 4/31 = (2 * 31 + 4)/31 = 66/31

Step 2: Rewrite the expression with the improper fractions: 9 4/31 - (6 8/31 + 2 4/31) = 289/31 - (194/31 + 66/31)

Step 3: Perform the addition inside the parentheses first: 289/31 - (194/31 + 66/31) = 289/31 - 260/31

Step 4: Now, perform the subtraction: 289/31 - 260/31 = (289 - 260)/31 = 29/31

So, the result of the expression is 29/31.
