Writing ratios in simplest form.
In this figure, it is easy to see that the ratio of yellows to greens is. If we put circles around each column of tiles
we can see that the ratio of yellow columns to green columns is.
Since the number of tiles never changed - only how we looked at them - this shows that the ratiosand are equivalent to each other. In other words,
Ratios can be reduced just like fractions!
