Note:
- Fraction = part of whole : Fraction = āĻāĻāĻž āĻ āĻāĻļ
- Numerator = taken part : āϞāĻŦ = āϞā§ā§ąāĻž āĻ āĻāĻļ
- Denominator = total parts : āĻšā§° = āĻŽā§āĻ āĻ āĻāĻļ
- Representation: shape, number line, set, words : āĻĒāĻĻā§āϧāϤāĻŋ: āĻāĻāĻžā§°, āϏāĻāĻā§āϝāĻž ā§°ā§āĻāĻž, āĻŦāϏā§āϤā§ā§° āĻā§āĻ, āĻļāĻŦā§āĻĻ
