Respuesta :

Answer:2/5 if you don’t include 8:20

3/4 if you include 8:20

Step-by-step explanation:

1. There are 20 times, and 8 times past 8:20, so it would be, 8/20 so simplified is, 2/5, (8 divided by 4, 20 divided by 4)

2. There are 20 different times, and 15 past 8:20 including 8:20, so it is 15/20, when simplified it is, 3/4, (15 divided by 5, over 20 divided by 5)
