Michelle has a recipe that asks for 2 1/2 cups of vegetable oil. she wants to use 2/3 that amount of oil use applesauce to replace the rest. how much will she use

This is a multiplication problem.

2 1/2 * 2/3 = 5/2 * 2/3 = 10/6

She will use 10/6 or 1 2/3 cups of vegetable oil (or applesauce idk).

Hope this helps, let me know if it's wrong!

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
