Josie practices piano for 1 2/5 hour on each 5 school days and 2 1/2 hours each day of the weekend. How long does she practice in a week.
Total practise time = 5 times 1 2/5 + 2 times 2 1/2
= 5(1.4) + 2(2.5)
= ....
or
5(7/5) + 2(5/2) =
things cancel nicely

To find out how long Josie practices in a week, we need to calculate the total practice time for the school days and the weekend separately, and then add them together.
Let's start with the school days:
Josie practices for 1 2/5 hours each day for 5 school days.
To find the total practice time for the school days, we need to multiply the practice time per day by the number of school days.
1 2/5 hours can be written as the improper fraction 7/5.
So, the total practice time for school days is:
7/5 * 5 = 7 hours
Now let's calculate the practice time for the weekend:
Josie practices for 2 1/2 hours each day for 2 days of the weekend.
To find the total practice time for the weekend, we need to multiply the practice time per day by the number of weekend days.
2 1/2 hours can be written as the improper fraction 5/2.
So, the total practice time for the weekend is:
5/2 * 2 = 5 hours
Finally, we can add the practice time for the school days and the weekend to find the total practice time for the week:
7 hours (school days) + 5 hours (weekend) = 12 hours
Therefore, Josie practices for a total of 12 hours in a week.
