Answer :
a. 1.52 hours a day of practice are needed by Matthew.
b. Subtraction and division are the needed operations.
Matthew has already completed 6 3/4 hours. Convert 6 3/4 to an improper fraction or decimal for easier calculations.
Convert 6 3/4 to a decimal: 6 3/4 = 6 + 0.75
= 6.75 hours
Subtract this from the total required hours: Remaining hours = Total hours - Completed hours Remaining hours
= 25 - 6.75
= 18.25 hours
To find out how many hours he needs to practice each day, divide the remaining hours by the number of days.
Perform the division: Daily practice hours = Remaining hours / Number of days Daily practice hours
= 18.25 / 12
≈ 1.52 hours per day
Subtraction to find out how many hours of practice remain. Division to determine how many hours he should practice each day.
