Final answer:
To change dissimilar fractions to similar fractions, we find a common denominator for each set of fractions and convert them accordingly, resulting in new fractions with the same denominators.
Step-by-step explanation:
The question asks to change dissimilar fractions into similar fractions, meaning fractions that have the same denominator. To do this, we need to find a common denominator for each set of fractions and convert them accordingly.
Example 1:
For the fractions 2/5 and 1/4, the common denominator is 20. After conversion, they become 8/20 and 5/20, respectively.
Example 2:
The fractions 3/8, 6/24, and 4/12 can all be converted to have a common denominator of 24, resulting in fractions 9/24, 6/24, and 8/24, respectively.
Example 3:
For the fractions 4/6 and 11/12, the common denominator is 12. They become 8/12 and 11/12 after conversion.
Example 4:
The fractions 2/5 and 8/45 can be converted to the common denominator 45, becoming 18/45 and 8/45, respectively.
Example 5:
Lastly, the fractions 3/6, 12/30, and 3/5 can all be converted to have a common denominator of 30, resulting in 15/30, 12/30, and 18/30, respectively.
