Step-by-step explanation

Since 152 students correspond to one-third of the total number of students at the school, we can use a rule of three to solve the exercise.


\begin{gathered} 152\text{ students}\rightarrow(1)/(3) \\ x\rightarrow1 \\ \text{ Because }(3)/(3)=1 \end{gathered}
\begin{gathered} x=\frac{1\cdot152\text{ students}}{(1)/(3)} \\ x=(1\cdot152)/((1)/(3))\text{ students} \\ x=(152)/((1)/(3))\text{ students} \\ x=((152)/(1))/((1)/(3))\text{ students} \\ x=(152\cdot3)/(1\cdot1)\text{ students} \\ x=(456)/(1)\text{ students} \\ x=456\text{ students} \end{gathered}Answer

There are 456 students at the school.
