# Description

Equivalent fractions (Using Proper Fractions)

Find corresponding Equivalent fractions:

Compare proper fractions in a circle with proper fractions in a square.

Increase or decrease the number of sections with 'pinch zoom'.

Open-ended explorations or guided options. (Select at: top bar)

(Or play with the Ahmes 2/n table of the RMP, like in the main video of the app)

(Or play with the table shown in the Akhmim Papyrus)
