The amount of blue color in the green paint is an illustration of ratios and proportions.

Cheryl's green paint has more blue color

The proportion of blue color is calculated as:

$\mathbf{Proportion = \frac{Blue}{Blue+ Yellow}}$

So, we have:

$\mathbf{Cheryl= \frac{16}{16+ 24}}$

$\mathbf{Cheryl= \frac{16}{40}}$

$\mathbf{Cheryl= 0.40}$

Express as percentage

$\mathbf{Cheryl= 40\%}$

$\mathbf{Rodney= \frac{6}{6+ 10}}$

$\mathbf{Rodney= \frac{6}{16}}$

$\mathbf{Rodney= 0.375}$

Express as percentage

$\mathbf{Rodney= 37.5\%}$

By comparison: 40% >37.5%

Hence, Cheryl's green paint has more blue color
