Trayvon recorded the number of minutes he spent practicing each swimming event over three days. He recorded his times in the table below.

Trayvon’s Swim Practice Times

Monday

Wednesday

Friday

Backstroke

12.5 min

15.67 min

9.32 min

Butterfly

14.333 min

12.1 min

10.78 min

Which statement explains how to find the event Trayvon spent more time practicing?

Compare the sum 12.50 + 15.67 + 9.32 = 37.49 to the sum 14.333 + 12.100 + 10.780 = 37.213; he spent more time practicing the backstroke than the butterfly.

Compare the sum 12.05 + 15.67 + 9.32 = 37.04 to the sum 14.333 + 12.001 + 10.078 = 36.412; he spent more time practicing the backstroke than the butterfly.

Compare the sum 12.500 + 14.333 = 26.833 to the sum 15.67 + 12.10 = 27.77 and to the sum 9.32 + 10.78 = 20.1; he spent more time practicing on Wednesday than on the other days.

Compare the sum 12.005 + 14.333 = 26.338 to the sum 15.67 + 12.01 = 27.68 and to the sum 9.32 + 10.78 = 20.1; he spent more time practicing on Wednesday than on the other days.
