Hello!
To find the percentage you divide the two numbers and then multiply by 100 to get the percentage.
Store 1
5/8=0.625
0.625=62.5%
Store 2
13/22≈0.59
0.59=59%
Store 3
22/30≈0.73
0.73=73%
Store 4
12/25=0.48
0.48=48%
As we can see from our percentages, 73% is the greatest. Therefore Store 3 is the correct answer.
I hope this helps!
