Answer 2

To solve the expression (2/7 + 1/81 + 3/4) ÷ (1 1/7), you should follow these steps:

Step 1: Find a common denominator for the fractions in the numerator (the top part of the fraction).

The common denominator for 7, 81, and 4 is 81.

Step 2: Rewrite each fraction with the common denominator of 81.

(2/7) becomes (2 * 11/77). (1/81) remains the same. (3/4) becomes (3 * 20/81).

So, the expression becomes:

(22/81 + 1/81 + 60/81) ÷ (1 1/7).

Step 3: Add the fractions in the numerator.

(22/81 + 1/81 + 60/81) = 83/81.

Step 4: Now, convert the mixed number 1 1/7 to an improper fraction.

1 1/7 = 7/7 + 1/7 = 8/7.

Step 5: Divide the result from step 3 by the improper fraction from step 4.

(83/81) ÷ (8/7) = (83/81) * (7/8).

Step 6: Multiply the fractions:

(83/81) * (7/8) = (83 * 7) / (81 * 8) = 581 / 648.

So, the result of the expression (2/7 + 1/81 + 3/4) ÷ (1 1/7) is 581/648 in its simplest form.
