Question

An art teacher has 70 1 / 2 pounds of clay and 20 students. Each student will get an equal amount of clay. How much clay does each student get? Write the answer as a mixed number.

Answer 1

Suppose each student gets x pounds of clay.

Given that the teacher has 70 1 / 2 pounds of clay and 20 students. Each student will get an equal amount of clay.

Therefore,

`\begin{gathered} 20x=70(1)/(2) \\ 20x=(141)/(2) \\ x=(141)/(40) \\ =3(21)/(40) \end{gathered}`

So, each student gets

`3\frac{21}{40\text{ }}pounds`
