The number of students who passed on the math exam was three-fourths of the total number of students who failed.

Alexxandr [17]

Answer:

one quarter of the total number of students will be those who failed their exam.

Step-by-step explanation:

Three - fourths = those who passed the exam

one quarter will be those who failed their exam

From the total number of the students.

Let's make an example

40 students who take the exam.

3 over 4 students from the total number of 40 take the exam and the result is passed and it mean 30 students passed in the exam.

1 over 4 students take the exam and the result is failed and it mean 10 students failed in the exam.

4 minus 3 over 4 will get the answer 1 over 4.

Use 1 over 4 to multiple with the total number of the students and that how you will get the answer for those who failed in their exam.

A student solved this problem and said the answer was hour. cindy rode her bike for hour and ran for hour. what was the total le

saw5 [17]

The answer would be a. Yes, the student’s answer is reasonable.

In the problem, it states that Cindy rode her bike for an hour and ran for an hour. Without the presence of the comma between rode her bike for an hour, and ran for an hour, this just means that Cindy only rode her bike and ran it for an hour.

The sentence can be written as Cindy rode her bike and ran for an hour. So, this gives an answer that Cindy only exercise for an hour.

Jessica had m beads. She used 18 of them to make a necklace for her mom. Then she used the rest to make k bracelets for her frie

Y_Kistochka [10]

The expression to represent this would be (m-18)/k.

We first subtract the 18 beads she used in her mother's bracelet from her beginning number, m. We then divide our result by k, the number of bracelets she made for her friends.
