Understanding Unlike Fractions
Unlike fractions are fractions that have different denominators. This means that the bottom numbers of the fractions are not the same, which makes them "unlike." Let's analyze the given options to identify which pairs of fractions are unlike.
Option A: 5/8 and 3/8
- Both fractions have the same denominator (8).
- Therefore, they are like fractions, not unlike.
Option B: 1/4 and 1/4
- Both fractions are identical, with the same numerator and denominator (1/4).
- These are also like fractions, not unlike.
Option C: 2/5 and 3/6
- The denominators are different (5 and 6).
- This makes them unlike fractions, as they do not share a common denominator.
Option D: 2/3 and 4/3
- Although the denominators are the same (3), the numerators are different (2 and 4).
- These are considered like fractions, as they have the same denominator.
Conclusion
The correct answer is option C (2/5 and 3/6). These fractions are unlike because they have different denominators. Understanding the difference between like and unlike fractions is essential for performing operations such as addition and subtraction, which require a common denominator.

To check if two fractions are equivalent, you multiply the numerator of the first fraction by the denominator of the second and vice versa. If the products are equal, the fractions are equivalent. For example, checking if 2/4 and 4/8 are equivalent involves confirming that 2 × 8 = 16 and 4 × 4 = 16.

The numerator is the top number in a fraction, which indicates how many parts of the whole are being considered. For example, in the fraction 3/4, the numerator is 3, meaning we have three parts of a total of four. Understanding the role of the numerator helps in grasping the concept of fractions as parts of a whole.
