The dissimilar fractions and similar fractions are noted as follows:
1. [tex]\frac{2}{3} $ and $ \frac{1}{3}[/tex] - Similar (S)
2. [tex]\frac{3}{4} $ and $ \frac{1}4}[/tex] - Similar (S)
3. [tex]\frac{4}{7} $ and $ \frac{7}{8}[/tex] - Dissimilar (D)
4. [tex]\frac{2}{5} $ and $ \frac{5}{11}[/tex] - Dissimilar (D)
5. [tex]\frac{7}{13} $ and $ \frac{7}{9}[/tex] - Dissimilar (D)
Note:
- Similar fractions have the same denominator. i.e. the bottom value of both fractions are the same.
- Dissimilar fractions have different value as denominator, i.e. the bottom value of both fractions are not the same.
Thus:
1. [tex]\frac{2}{3} $ and $ \frac{1}{3}[/tex] - They have equal denominator. Both fractions are similar (S).
2. [tex]\frac{3}{4} $ and $ \frac{1}4}[/tex] - They have equal denominator. Both fractions are similar (S).
3. [tex]\frac{4}{7} $ and $ \frac{7}{8}[/tex] - They have equal denominator. Both fractions are dissimilar (D).
4. [tex]\frac{2}{5} $ and $ \frac{5}{11}[/tex] - They have equal denominator. Both fractions are dissimilar (D).
5. [tex]\frac{7}{13} $ and $ \frac{7}{9}[/tex] - They have equal denominator. Both fractions are dissimilar (D).
Therefore, the fractions in 1 and 2 are similar (S) while those in 3, 4, and 5 are dissimilar (D).
