Answer:
17/24
Step-by-step Explanation:
The total fraction of the pie eaten = fraction of pie Katelyn ate + fraction of pie Chad ate.
Total fraction of the pie eaten = 1/3 + 3/8
To add 2 fractions they should have the same denominator.
So, let's find the LCM of 3 & 8.
LCM of 3 & 8 = 24
Lily: 1/3 = 1*8/3*8 = 8/24
Chad: 3/8 = 3*3/8*3 = 9/24
8/24 +9/24 = 17/24
Total fraction of the pie eaten = 17/24
