Answer 2

To solve the equation, we need to evaluate the expression 1-3/7 * 2 5/8. Let's break it down step by step:

1. Convert the mixed numbers to improper fractions: 3/7 = (7 * 1 + 3)/7 = 10/7 2 5/8 = (8 * 2 + 5)/8 = 21/8

2. Multiply 10/7 by 21/8: (10/7) * (21/8) = (10 * 21) / (7 * 8) = 210/56

3. Simplify the fraction: 210/56 = 15/4

4. Subtract 15/4 from 1: 1 - 15/4 = 4/4 - 15/4 = (4 - 15)/4 = -11/4

Therefore, the solution to the equation 1-3/7 * 2 5/8 is -11/4.
