Ratios and proportions
Would you rather go to a college with a high teacher-to-student ratio or a low one? What about the ratio of girls-to-boys? What is the ratio of eggs to butter in your favorite dessert?
Ratios show up EVERYWHERE in life. This tutorial introduces you to what they (and proportions) are and how to make good use of them!
What a ratio is. Simple ratio problems.
Ratios as Fractions in Simplest Form
Simplifying Rates and Ratios
In this example, we are given a ratio and then asked to apply that ratio to solve a problem. No problem!
Let's solve this word problem using what we know about ratios so far.
Practice solving basic ratio word problems.
We're displaying ratios in a table format here, and then asking: given a ratio, solve for equivalent ratios. Here are a few examples to practice on.
Let's compare 2 tables of ratios and interpret them to solve the word problem. This is a fun!
In this example we'll plot points on the x and y axis to reflect the given ratios.
Practice filling out tables of equivalent ratios.
