On a test, Hailey answered 12 out of the first 15 problems correctly.If this rate continues, how many of the next 25 problems will she answer correctly?
12/15 = 0.8
25 * 0.8 = ?
To find out how many of the next 25 problems Hailey will answer correctly, we need to figure out her success rate and then apply it to the remaining questions.
First, we determine Hailey's success rate based on her performance in the first set of questions. She answered 12 out of 15 correctly, so we divide the number of correct answers (12) by the total number of questions (15):
Success rate = (Number of correct answers / Total number of questions)
= (12 / 15)
= 0.8
Now we apply this success rate to the remaining 25 questions to find out how many she will answer correctly:
Number of correct answers in the next 25 questions = Success rate * Total number of questions
= 0.8 * 25
= 20
Therefore, if Hailey's success rate continues, she will answer 20 out of the next 25 problems correctly.
