This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - Direct proportion means as one value increases, the other increases; solve using cross-multiplication (a/b = c/d). - Inverse proportion means as one value increases, the other decreases; solve by finding the constant product (e.g., worker-hours). - A common exam trap is incorrectly applying direct proportion cross-multiplication to an inverse relationship problem. - For problems with a total quantity and a ratio (e.g., 3:5 with a total of 800), sum the ratio parts first (3+5=8) to find the value of one 'part'. - Mnemonic: "More means more, so make a cross" for direct proportions, and "More means less, so multiply across" for inverse proportions.
