Question

Atwood Ridge middle school 30% of the teachers are male if the 21 teachers are male how many total teachers are in the school

Answer 1

Taking x as the total number of teachers, we know that 30% of x is 21, it means that 0.3 times x is 21. We can use this information to find x, it means, the total number of teachers:

`\begin{gathered} 0.3x=21 \\ x=(21)/(0.3) \\ x=70 \end{gathered}`

There are 70 teachers in the school.
