Self-tutoring about ratios: the tutor reflects about preparing oatmeal.
The ratio of oatmeal to water, with the brand I use, is 1 and 1/3 cup to 3 cups. As such, it’s a less convenient ratio to scale up or down than some.
Yet, 1 and 1/3 to 3 is actually 4/3 to 9/3, so it’s 4 to 9. That’s an easy ratio to scale up or down. In my case, I scale it up: 2 cups to 4 and 1/2 cups, or 4/2 to 9/2.Jack of Oracle Tutoring by Jack and Diane, Campbell River, BC.
