Question

The average person spends about 1/10 of their walking hours with their eyes closed. If Mrs. James was awake for 15 1/2 hours today, how much more time did she have her eyes open than closed.? PLEASE HELP TYSM!!!

Answer 1

she had here eyes open for 12.4 more hours than she had them closed

Explanation:

1/10 eyes closed = 9/10 eyes open

9/10 is 90% is 0.9

1/10 is 10% is 0.1

15 1/2 is 15.5

15.5 x 0.9 = 13.95

15.5 x 0.1 = 1.55

13.95-1.55 = 12.4
