Answer:
The result is 1/24

Explanation:
First step is to get the common denominator:
The common denominator here will be 8*9 = 72
Therefore:
3/8 = 27/72
3/9 = 24/72

Second step is to do the subtraction:
27/72 - 24/72 = (27-24) / 72 = 3/72

The last step is to simplify the result:
3/72 = 1/24

Hope this helps :)
