  • I'm NOT asking about the algebra that I already know. It's NOT intuitive why 3 pears x 4 tangelos = 6 quinces x 2 raspberries $\iff$ 3 pears/6 quinces = 2 raspberries/4 tangelos.
  • I stumbled [the picture below](https://www.ck12.org/assessment/tools/geometry-tool/plix.html?eId=MAT.ALG.703.04&questionId=5446cde4da2cfe0c74e9e61e&artifactID=2040326&plix_redirect=1), but how does it proffer intuition?
