<h2><em><u>The answers:</u></em></h2>
1.
- Similar (S)
2.
- Similar (S)
3.
- Dissimilar (D)
4.
- Dissimilar (D)
5.
- 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.
- They have equal denominator. <u><em>Both fractions are similar (S).</em></u>
2.
- They have equal denominator. <em><u>Both fractions are similar (S).</u></em>
3.
- They have equal denominator. <em><u>Both fractions are dissimilar (D).</u></em>
4.
- They have equal denominator. <u><em>Both fractions are dissimilar (D).</em></u>
5.
- They have equal denominator. <em><u>Both fractions are dissimilar (D).</u></em>
Therefore, the fractions in <em><u>1 and 2 are similar (S)</u></em> while those in <em><u>3, 4, and 5 are dissimilar (D).</u></em>
