To find out how many days the treats will last for Jingles:
If Sammy purchased 25 doggie biscuits and gives Sophie 2 ½ treats every day:
First, find the total number of treats Sophie gets daily: 2 ½ = 2.5 treats per day.
Then divide the total number of treats purchased (25) by the number of treats given per day (2.5):
25 treats/2.5 treats/day = 10 days.
Therefore, the treats will last for 10 days for Sophie.
