Let w represent white mice and G represent gray mice then,
from question we have:
$$\frac{1}{2}$$ W = $$\frac{1}{8}$$ T
or, w = $$\frac{2}{8}$$ T = $$\frac{1}{4}$$ T

$$\frac{1}{3}$$ G = $$\frac{1}{9}$$ T
or, G = $$\frac{3}{9}$$ T = $$\frac{1}{3}$$ T

Hence $$\frac{1}{4}$$ T divided by $$\frac{1}{3}$$ T = $$\frac{3}{4}$$
