Put these fractions in order from least to greatest. 1/3, 2/8, 1/2, 3/3, 6/8
Correct Answer
2/8, 1/3, 1/2, 6/8, 3/3Explanation
The fractions are ordered from least to greatest based on their decimal equivalents. To compare fractions with different denominators, we can convert them to fractions with a common denominator. In this case, we can convert all the fractions to eighths. The fractions 2/8, 1/3, 1/2, 6/8, and 3/3 can be converted to 1/4, 8/24, 12/24, 6/8, and 8/8 respectively. Ordering these fractions from least to greatest gives 1/4, 6/8, 8/24, 12/24, and 8/8. Simplifying these fractions further, we get 1/4, 3/4, 1/3, 1/2, and 1. Therefore, the correct order is 2/8, 1/3, 1/2, 6/8, 3/3.Rate this question:

9/10 - 5/10 =
Correct Answer
4/10, 2/5Explanation
The given expression is a subtraction of two fractions. To subtract fractions, we need a common denominator. In this case, the common denominator is 10. So, we rewrite 9/10 as 9/10 * 1/1 and 5/10 as 5/10 * 1/1. Now, we can subtract the numerators and keep the common denominator to get 4/10. Simplifying this fraction gives us 2/5. Therefore, the answer is 4/10, 2/5.Rate this question:

Write 2 1/4 as an improper fraction.
Correct Answer
9/4Explanation
To convert a mixed number to an improper fraction, we multiply the whole number by the denominator of the fraction and add the numerator. In this case, we multiply 2 by 4 (the denominator) and add the numerator 1, which gives us 9. Therefore, the improper fraction equivalent of 2 1/4 is 9/4.Rate this question:

Add 6/12 + 1/6.
Correct Answer
8/12, 2/3Explanation
To add fractions, we need to have a common denominator. In this case, the common denominator is 12. We can convert 6/12 to 1/2 by dividing both the numerator and denominator by 6. So, 6/12 + 1/6 becomes 1/2 + 1/6. To add these fractions, we need to find a common denominator, which is 6. We can convert 1/2 to 3/6 by multiplying both the numerator and denominator by 3. Now, we have 3/6 + 1/6, which equals 4/6. Simplifying this fraction, we get 2/3. Therefore, the answer is 8/12, 2/3.Rate this question:
