Answer : The number of full packs filled are, 666 and more tennis balls needed to make a full pack is, 1
Step-by-step explanation :
Total number of tennis balls = 2000
1 pack contains 3 balls.
Total number of packs filled with balls =
![(2000)/(3)=666(2)/(3)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/fb4minl04t3qcmgsdqk8smt22ma9vw1zc1.png)
This means that, number of full packs filled = 666
Remaining balls after filling packs = 2
Thus, the number of balls needed for the last full pack = 3 - 2 = 1
Hence, the number of full packs filled are, 666 and more tennis balls needed to make a full pack is, 1
