John who is an amateur golfer spends 3 hours every day practicing golf. What percentage of his waking hours does John spend practicing golf if he sleeps 9 hours a day?
24-9=15 3/15= 0.2 0.2 x 100 = 20% spent practicing
Yes.
Yes, assuming he is practicing while he is awake. Many golfers play as if they are asleep.
Mickey spent 3 1/4
hours practicing his trumpet. He needs to spend
5 1/2
hours to receive an A in band. How many more hours does Mickey need to spend practicing his trumpet?
To find the percentage of John's waking hours spent practicing golf, we first need to calculate his waking hours. Since John sleeps for 9 hours a day, his waking hours can be calculated by subtracting his sleeping hours from 24 hours in a day:
Waking hours = 24 hours - 9 hours = 15 hours
Now that we know John has 15 waking hours, we can determine the percentage of his waking hours spent practicing golf. John spends 3 hours practicing golf every day:
Percentage spent practicing golf = (hours practicing golf / waking hours) x 100
Percentage spent practicing golf = (3 hours / 15 hours) x 100
Simplifying this equation, we get:
Percentage spent practicing golf = 0.2 x 100 = 20%
Therefore, John spends 20% of his waking hours practicing golf.
