Three 241

Three-fifths of the t-shirts in a t-shirt shop are blue. Five-eights of those T-shirts are on sale. One-third of the blue of the blue shirts that are on sale are size medium. What fraction of the shop's blue T-shirts are on sale and size medium?

Final Answer:

c =  1/8

Step-by-step explanation:

$$\begin{gathered} a=\frac{3}{5}=0.6 \\ b=\frac{5}{8}\cdot a=\frac{5}{8}\cdot \frac{3}{5}=\frac{5\cdot 3}{8\cdot 5}=\frac{15}{40}=\frac{3}{8}=0.375 \\ c=\frac{1}{3}\cdot b=\frac{1}{3}\cdot \frac{3}{8}=\frac{1\cdot 3}{3\cdot 8}=\frac{3}{24}=\frac{1}{8}=0.125 \end{gathered}$$
