Answer: 3/4
Explanation:
Amount of chicken ordered = 3
Fraction eaten by Alex = 5/8
Fraction eaten by Chase = 7/8
Fraction eaten by Ella = 6/8
The chicken ate by the three friends will be:
= 5/8 + 7/8 + 6/8
= 18/8
= 2 2/8
= 2 1/4
Now, the chicken left for the forty friend will be:
= 3 - 2 1/4
= 3/4
