Comparable reasoning patterns exist for inverse proportion. Typical Solutions Someone with knowledge about the area of triangles might reason: “Initially the area of the water forming the triangle is 12 since ½ * 4 * 6 = 12. The amount of water doesn’t change so the area won’t change. So the answer is 3 because ½ … Webbclarify that proportional reasoning is more about the use of number sense than formal, procedural solving of proportions.
