Phil needs to practice free throws 7/10 of an hour each day. If he has already practiced 3/10 of an hour today, how much longer does he need to practice?
7/10 - 3/10 = ??
We'll be glad to check your answer.
7/10-3/10=4/10 and if u want to simplify the fraction it would be the following 4/10 divided by 2/2 = 2/5
To find out how much longer Phil needs to practice, we can subtract the time he has already practiced from the total time he needs to practice.
First, let's convert the fractions to a common denominator. The denominators for 10 and 10 are the same, so we don't need to make any changes there.
Phil needs to practice 7/10 of an hour each day, and he has already practiced 3/10 of an hour.
To find the remaining time, we subtract the time he has already practiced from the total time he needs to practice:
Total time - Time already practiced = Remaining time
7/10 - 3/10 = 4/10
So Phil needs to practice for an additional 4/10 of an hour.
However, we want to convert this fraction to a more familiar time unit such as minutes or hours. We can convert 4/10 to a decimal by dividing the numerator (4) by the denominator (10):
4 ÷ 10 = 0.4
So Phil needs to practice for an additional 0.4 hours, which is the same as 24 minutes (since there are 60 minutes in an hour).
Therefore, Phil needs to practice for an additional 24 minutes.
