Final answer:
To find the difference of fractions, represent them on a number line, find equivalent fractions with a common denominator, and subtract the numerators while keeping the common denominator.
Step-by-step explanation:
To find the difference of fractions using a number line and equivalent fractions, you can follow these steps:
- Represent the fractions on a number line. For example, if you have the fractions 1/2 and 1/4, you can plot them on a number line.
- Find equivalent fractions with a common denominator. In this case, both 1/2 and 1/4 can be rewritten with a common denominator of 4.
- Subtract the fractions by subtracting the numerators and keeping the common denominator. In this case, the difference is 1/4.
Therefore, the difference of the fractions 1/2 and 1/4 is 1/4, which corresponds to answer option B. -1.
