A product tester measures four different sizes of shampoo bottles to see if they are filled accurately. The table shows the results. Which sample had the least percent error?

Sample 1:The error is 0.1 out of 20. 0.1 / 20 = 0.005 = 0.5 %

Sample 2:The error is 0.1 out of 32. 0.1 / 32 = 0.003125 = 0.3125 %

Sample 3:The error is 0.1 out of 36. 0.1 / 36 = 0.00277 = 0.277 %

Sample 4:The error is 0.1 out of 64. 0.1 / 64 = 0.0015625 = 0.15 %

The smallest percent is the least percent error.

Is there anything here that you couldn't do on your own?
