Correct Answer
A. 16/11Explanation
When dividing fractions, we invert the second fraction and multiply it with the first fraction. In this case, we have 8/11 divided by 1/2. Inverting 1/2 gives us 2/1. Multiplying 8/11 with 2/1, we get (8/11) * (2/1) = 16/11. Therefore, the correct answer is 16/11.Rate this question:

Correct Answer
A. 11/28Explanation
The given expression is a subtraction of two fractions. To subtract fractions, we need to have a common denominator. The common denominator for 14 and 4 is 28. So, we convert the fractions 9/14 and 1/4 into fractions with a denominator of 28. 9/14 becomes 18/28 and 1/4 becomes 7/28. Now, we can subtract the fractions by subtracting their numerators while keeping the denominator the same. 18/28 - 7/28 equals 11/28. Therefore, the correct answer is 11/28.Rate this question:

A. 6 2/3Explanation
To divide a whole number by a fraction, we can multiply the whole number by the reciprocal of the fraction. In this case, we have 5 divided by 3/4. The reciprocal of 3/4 is 4/3. Multiplying 5 by 4/3 gives us 20/3, which is equivalent to 6 2/3. Therefore, the correct answer is 6 2/3.Rate this question:

Correct Answer
A. 7Explanation
The given expression is 11 multiplied by 7/11. When we multiply a number by a fraction, we can simplify the expression by canceling out any common factors between the numerator and denominator. In this case, the number 11 can be canceled out, leaving us with 7 as the result. Therefore, the correct answer is 7.Rate this question:

Correct Answer
A. 13/18Explanation
To find the sum of fractions, we need to have a common denominator. In this case, the common denominator is 18. Converting 1/6 to have a denominator of 18 gives us 3/18. Converting 5/9 gives us 10/18. Adding these fractions together gives us 13/18.Rate this question:

A. 2 1/3Explanation
The given expression is 3 - 2/3. To subtract a fraction from a whole number, we need to convert the whole number into a fraction with the same denominator as the fraction. In this case, the denominator is 3. So, we convert 3 into a fraction by multiplying it by 3/3, which gives us 9/3. Now, we can subtract the fractions: 9/3 - 2/3 = 7/3. To express this as a mixed number, we divide the numerator (7) by the denominator (3), which gives us 2 with a remainder of 1. Hence, the answer is 2 1/3.Rate this question:

Correct Answer
A. 1/9Explanation
To subtract fractions, we need to have a common denominator. In this case, the common denominator is 9. So, we rewrite 7/9 as 7/9 * 3/3 and 2/3 as 2/3 * 3/3. This gives us (7 * 3 - 2 * 3) / 9 = 21/27 - 6/27 = 15/27. Simplifying this fraction by dividing both the numerator and denominator by their greatest common divisor, which is 3, we get 5/9. Therefore, the correct answer is 5/27.Rate this question:
