To find the correct answer, let's break down the calculations for each expression:

1. Calculation for 1 3/5 - 5/6:
- Convert the mixed number 1 3/5 into an improper fraction: 1 * 5 + 3 = 8/5.
- Find a common denominator for 5 and 6, which is 30.
- Multiply the fractions by the appropriate factors:
- (8/5) * (6/6) = 48/30
- (5/6) * (5/5) = 25/30
- Subtract the fractions: (48/30) - (25/30) = 23/30.

2. Calculation for 1/3/5 - 5/6:
- To avoid confusion, let's rewrite the expression as (1/3) / 5.
- Multiply the numerator and denominator of (1/3) by 5: (1/3) * (5/5) = 5/15.
- Find a common denominator for 15 and 6, which is 30.
- Multiply the fractions by the appropriate factors:
- (5/15) * (2/2) = 10/30
- (5/6) * (5/5) = 25/30
- Subtract the fractions: (10/30) - (25/30) = -15/30 or -1/2.

Comparing the two calculations we just performed, it can be concluded that the correct answer is 23/30 for the expression 1 3/5 - 5/6. Therefore, the option with 2/5 is incorrect.
