To find out how many hours Julie studies in total over the three days, we need to add the fractions together.
The given amounts of time Julie spends studying are 3/4 hour on Monday, 1/6 hour on Tuesday, and 2/3 hour on Wednesday.
To add fractions, we need to find a common denominator. In this case, the smallest common denominator is 12.
To make the denominators all equal to 12:
- Multiply the numerator and denominator of 3/4 by 3, resulting in 9/12.
- Multiply the numerator and denominator of 1/6 by 2, resulting in 2/12.
- The fraction 2/3 already has a denominator of 3, so just multiply the numerator and denominator by 4, resulting in 8/12.
Now we can add the fractions together:
9/12 + 2/12 + 8/12 = 19/12
However, we want the answer in hours, so let's convert the fraction to a mixed number:
19/12 = 1 and 7/12
Therefore, Julie studies for a total of 1 hour and 7/12 hours over the three days.
