The ratio of girls to boys in Sam's math class can be calculated by taking the number of girls and dividing it by the number of boys:
Ratio of girls to boys = Number of girls / Number of boys
Ratio of girls to boys = 16 / 12
Ratio of girls to boys = 4 / 3
Therefore, the ratio of the number of girls in Sam's class to the number of boys is 4:3.
