Answer 1

(1 3/5+2 1/5):1 9/10 (1 7/10-4/5):3/7=3 4/52.1 7/10-4/5=1 7/10-8/10=9/10.3 4/5:1 9/10=19/5×10/19=24.9/10:3/7=9/10×7/3=21/10.

Answer 2

Let's break down the expression step by step:

1. Addition of Mixed Numbers: (1 3/5 + 2 1/5) = (8/5 + 11/5) = 19/5

2. Subtraction of Mixed Numbers: (1 7/10 - 4/5) = (17/10 - 4/5) = (17/10 - 8/10) = 9/10

3. Addition of Fractions: (1 9/10 + 9/10) = (19/10 + 9/10) = 28/10 = 14/5

4. Division of Fractions: (14/5) / (3/7) = (14/5) * (7/3) = (14 * 7) / (5 * 3) = 98/15

So, the final result of the given expression is 98/15.
