Three-fifths of the students in a room are girls. One-third of the girls have blond hair. One-half of the boys have brown hair.
yan [13]

Answer:

a. Of all the students, \frac{1}{5} are girls with blond hair.

b. Of all the students, \frac{1}{5} are boys without brown hair.

Step-by-step explanation:

a. You know that \frac{3}{5} of the students are girls (This means that \frac{2}{5} of the studes are boys) and \frac{1}{3} of these girls have blond hair.

Then, \frac{1}{3} of \frac{3}{5} is:

(\frac{3}{5})(\frac{1}{3})=\frac{1}{5}

Therefore, of all the students, \frac{1}{5} are girls with blond hair.

b. You know that \frac{1}{2} of the boys have brown hair.

Then, \frac{1}{2} of \frac{2}{5} is:

(\frac{2}{5})(\frac{1}{2})=\frac{1}{5}

Of all the students, \frac{1}{5} are boys without brown hair.
