OpenStudy (freckles):

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

OpenStudy (freckles):

6 parts~252 peeps

OpenStudy (freckles):

males are 3 parts of that 6 parts

OpenStudy (freckles):

pretend that is an equation

OpenStudy (freckles):

how would you get 3 parts~? peeps

OpenStudy (freckles):

think about dividing something on both sides

OpenStudy (freckles):

6/what =3

OpenStudy (calculusxy):

2

OpenStudy (freckles):

so divide both sides by 2

OpenStudy (calculusxy):

126

OpenStudy (freckles):

\[\frac{6}{2} \text{parts} \text{ ~ }\frac{252}{2} \text{peeps}\]

OpenStudy (calculusxy):

ok thanks :)

OpenStudy (freckles):

oh and you needed the percentage

OpenStudy (calculusxy):

c

OpenStudy (freckles):

take that number 126 and divide it by total people in all lol which makes sense because you have male:everyone else=3:3

OpenStudy (freckles):

that means males are half the population
