Divide 4/5 by 2/3
Correct Answer
6/5
1 1/5
1 and 1/5Explanation
When dividing fractions, we multiply the first fraction by the reciprocal of the second fraction. In this case, we have (4/5) ÷ (2/3). To find the reciprocal of 2/3, we flip it, resulting in 3/2. Then, we multiply 4/5 by 3/2, which gives us 12/10 or 6/5. Therefore, the correct answer is 6/5.Rate this question:

The arithmetic average of A and B is 14. If C=11, what is the average of all three numbers?
Correct Answer
13Explanation
If the arithmetic average of A and B is 14, it means that the sum of A and B is 28. Since C is given as 11, the sum of all three numbers is 28 + 11 = 39. To find the average, we divide the sum by the number of values, which in this case is 3. Therefore, the average of all three numbers is 39/3 = 13.Rate this question:

On a history test with 50 test items, a student got 8 wrong. What is the percentage grade for the test?
Correct Answer
84
84%
84 percentExplanation
The student got 8 out of 50 questions wrong on the test. To calculate the percentage grade, we need to find the percentage of correct answers. The number of correct answers can be calculated by subtracting the number of wrong answers from the total number of questions. So, the student got 42 questions correct (50 - 8 = 42). To find the percentage, we divide the number of correct answers by the total number of questions and multiply by 100. Therefore, the student's percentage grade is 84% (42/50 * 100 = 84%).Rate this question:
