Use division to find unit rates and ratios in proportional relationships such as speed, density, price, recipes, and student teacher ratio.

7.3B

Estimate and find solutions to application problems involving proportional relationships such as similarity, scaling, unit costs, and related measurement units.

Act Three

- Teacher noteIf 1 inch = 26 mm and the big ant measured 9 inches then using conversions

9 inches would equal 234 mm.

Using a proportion, students can calculate the percentage.

X/100 = 235/13

X = 1807. 69

The BIG ant would measure 1,807.7 percent larger than an actual ant.
