Rachel has been studying for her math test. In 15 minutes she finished 7 12 questions. How many questions does she answer in one minute?(1 point) Responses 2 questions 2 questions 2 minutes 2 minutes 12 of a question 1 half of a question 12 of a minute
To find the number of questions Rachel answers in one minute, divide the total number of questions she answered (7) by the total amount of time she spent studying (15 minutes).
7 questions / 15 minutes = <<7/15=0.46667>>0.47 questions per minute
So Rachel answers approximately 0.47 questions in one minute.

To find out how many questions Rachel answers in one minute, we can use the concept of unit rates.
Given that Rachel finished 12 questions in 15 minutes, we can set up a proportion:
12 questions / 15 minutes = x questions / 1 minute
Cross-multiplying, we get:
15 * x = 12 * 1
15x = 12
Dividing both sides by 15:
x = 12 / 15
Simplifying the fraction:
x = 4 / 5
So, Rachel answers 4/5 or 0.8 questions in one minute.
To find out how many questions Rachel answers in one minute, we can divide the number of questions she answered in 15 minutes by 15.
Rachel finished 7 12 questions in 15 minutes.
So, to find out how many questions she answers in one minute, we divide the total number of questions (7 12) by the total number of minutes (15):
7 12 / 15 = 1 half of a question.
Therefore, Rachel answers approximately 1 half of a question in one minute.
