in a 24- hour period, Grace spends 8 hours sleeping, 8 hours at school, 2 hours at dance class, and the rest of the time with her family. what percentage of her day is used for family time?
Well you would start with 24 subtract 8 hrs of sleeping (24-8) to get 16. Then 16 - 8 hours of school, gets you to 8. Then 8 - 2 is 6. Then divide 6 by 24 getting 0.25 and convert to a percentage: 25%
