Answer 2

To solve the given expression, let's break it down step by step:

Step 1: Convert mixed numbers to improper fractions: 6 4/7 = (7 * 6 + 4) / 7 = 46/7 1 1/5 = (5 * 1 + 1) / 5 = 6/5 3 3/7 = (7 * 3 + 3) / 7 = 24/7

Step 2: Simplify the expression: (46/7) + (6/5) + (24/7) * (1/5)

Step 3: Multiply the fractions: (46/7) + (6/5) + (24/7) * (1/5) = (46/7) + (6/5) + (24/35)

Step 4: Find a common denominator for the fractions: The common denominator is 35, so we need to convert all fractions to have a denominator of 35.

(46/7) + (6/5) + (24/7) * (1/5) = (46/7) * (5/5) + (6/5) * (7/7) + (24/7) * (1/5) = (230/35) + (42/35) + (24/35)

Step 5: Add the fractions: (230/35) + (42/35) + (24/35) = (230 + 42 + 24) / 35 = 296/35

Step 6: Simplify the fraction, if possible: 296/35 = 8 16/35

Therefore, 6 4/7 + 1 1/5 + 3 3/7 × 1/5 = 8 16/35.
