Julia studied math for 3 1/2 hours during the 4 days before her last math test. What was the average amount of time she studied each day?
Divide:
4 / 3 1/2 = ?
3 1/2 divided by 4 = ?
2 1/2
To find the average amount of time Julia studied each day, we need to divide the total time she studied by the number of days.
First, let's calculate the total time Julia studied.
Julia studied math for 3 1/2 hours during the 4 days before her last math test.
To express this as a mixed number, we can convert 3 1/2 to an improper fraction.
Multiplying the whole number (3) by the denominator (2) and adding the numerator (1), we get 7.
So, 3 1/2 is equivalent to 7/2.
Now, we can calculate the total time.
Total time = 7/2 hours * 4 days
To multiply fractions, we multiply the numerators together and the denominators together.
Total time = (7 * 4) / (2 * 1) hours
Total time = 28 / 2 hours
Simplifying the fraction, we get:
Total time = 14 hours
Now that we have the total time Julia studied, we can find the average by dividing it by the number of days.
Average time = Total time / number of days
Average time = 14 hours / 4 days
Dividing 14 by 4, we get:
Average time = 3.5 hours per day
Therefore, the average amount of time Julia studied each day was 3.5 hours.
