\[\text{ #males }+\text{ #females}+\text{#teachers}=252 \\ \]

\[\text{# males}:\text{#females}:\text{#teachers}=3:2:1 \\ \text{ this means we have } 3+2+1 \text{parts } \text{ or } \text{ 6 parts } \\ \text{ altogether we have } 252 \text {peeps} \\ \text{ so your } 6 \text{ parts } ~252 \text{ peeps}\]
