Answer 3

To solve the given expression, let's break down the steps:

Step 1: Convert mixed numbers to improper fractions. 7 7/8 = (8 * 7) + 7 = 56 + 7 = 63/8 2 5/11 = (11 * 2) + 5 = 22 + 5 = 27/11 2 6/11 = (11 * 2) + 6 = 22 + 6 = 28/11

Step 2: Substitute the improper fractions back into the expression. 7 7/8 - (2 5/11 + 2 6/11) = 63/8 - (27/11 + 28/11)

Step 3: Find a common denominator for the fractions inside the parentheses, which is 11 * 8 = 88. Convert the fractions to have the common denominator: 27/11 = (27/11) * (8/8) = 216/88 28/11 = (28/11) * (8/8) = 224/88

Step 4: Perform the addition inside the parentheses. 27/11 + 28/11 = (216/88) + (224/88) = (216 + 224)/88 = 440/88 = 5

Step 5: Substitute the result back into the expression and perform the subtraction. 63/8 - 5 = (63/8) - (440/88)

Step 6: Find a common denominator for the fractions in the subtraction. The common denominator of 8 and 88 is 8 * 11 = 88.

Step 7: Convert the fractions to have the common denominator. 63/8 = (63/8) * (11/11) = 693/88 440/88 = 440/88

Step 8: Perform the subtraction. (693/88) - (440/88) = (693 - 440)/88 = 253/88

So, 7 7/8 - (2 5/11 + 2 6/11) = 253/88.
