Hey there!
The answer is [tex]\frac{19}{30}[/tex]
To solve this we use subtraction, because "the difference" represents subtraction, so:
[tex]\frac{5}{6} - \frac{1}{5}[/tex]
Now, we must find a common denominator, and we can see that [tex]6[/tex] and [tex]5[/tex] both go into [tex]30[/tex]. To get to [tex]30[/tex], we multiplied the first fraction by 5 and the second by 6, so we now have:
[tex]\frac{25}{30} - \frac{6}{30}[/tex]
This is equal to [tex]\frac{19}{30}[/tex]
Hope it helps and have a great day!
