Answer 2

To calculate the expression (18 1/2 - 13 7/9) * 1/85, you can follow these steps:

1. Convert the mixed numbers to improper fractions:

   • 18 1/2 = 37/2
   • 13 7/9 = 124/9

2. Subtract the two fractions: (37/2 - 124/9)

3. Find a common denominator, which in this case is 18: To make the denominators equal, you can multiply the first fraction by 9 and the second fraction by 2: (37/2 * 9/9 - 124/9 * 2/2) (333/18 - 248/18)

4. Subtract the numerators: (333/18 - 248/18) = (333 - 248) / 18 = 85/18

5. Now, multiply the result by 1/85: (85/18) * (1/85) = (85/18) / (85/1)

6. To divide by a fraction, you can multiply by its reciprocal: (85/18) * (1/85) = (85/18) * (1/85/1) = (85/18) * (1 * 1/85) = (85/18) * (1/85) = 85/ (18 * 85) = 85/1530

So, the result of the expression (18 1/2 - 13 7/9) * 1/85 is 85/1530, which can be simplified further if needed.
