To identify unlike fractions, you need to compare their denominators. Here's how:
1. The denominators are different numbers: If two fractions have different denominators, they are considered unlike fractions. For example, 1/3 and 2/5 are unlike fractions because their denominators (3 and 5) are different.
2. The denominators are the same number: If two fractions have the same denominator, they are considered like fractions. For instance, 1/4 and 3/4 are like fractions because their denominators are both 4.
Therefore, the correct answer to the question "How are unlike fractions identified?" is:
- OA. The denominators are different numbers.
