Answer:
Springtown Cafe
Explanation:
If you want to be sure, find a common denominator. 9 and 10 are the denominators of each fraction. Find the multiples of each (9's multiples would be 9, 18, 27, etc.) and find a common multiple between the two. In this case, it would be 90. Multiply the denominator to get the common denominator. 9 x 10 = 90, 10 x 9 = 90. Remember to multiply both the top and bottom.
5/9 = 50/90
3/10 = 27/90
Now, we can clearly see that 5/9 is larger than 3/10.
So, Springtown cafe has a greater fraction of customers who left good tips.
