Answer 3

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

Step 1: Simplify the division operation 8 2/5 ÷ 2 1/10 To divide mixed numbers, we convert them to improper fractions: 8 2/5 = (8 * 5 + 2)/5 = 42/5 2 1/10 = (2 * 10 + 1)/10 = 21/10

Now we can rewrite the expression: 42/5 ÷ 21/10

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction: 42/5 * 10/21

Step 2: Simplify the multiplication operation 3 4/7 * 1 2/5 Again, convert the mixed numbers to improper fractions: 3 4/7 = (3 * 7 + 4)/7 = 25/7 1 2/5 = (1 * 5 + 2)/5 = 7/5

Now we can rewrite the expression: 25/7 * 7/5

Step 3: Perform the multiplication and division operations Now we can simplify the expression further: (42/5 * 10/21) + (25/7 * 7/5)

Multiply the fractions: (420/105) + (175/35)

Simplify the fractions: 4 + 5

The final result is 9.
