Answer:
The correct answer is C. 2 1/4 hours.
Step-by-step explanation:
1. Let's review all the information provided for answering the question properly:
Time Mara spent on her science homework = 1 1/2 hours
Science homework = 2/3 of the total time on her homework
Time Mara spent on her homework = x
2. For calculating the total time Mara spent on her homework, we make this calculation using the Rule of Three Simple:
x = (1 1/2)/2/3
x = 3/2 / 2/3 (1 1/2 = 3/2)
x = 3/2 / 2/3
x = 3/2 * 3/2 = 9/4
x = 9/4 = 2 1/4
x = 2 1/4 hours
