so since 144 students is what our 60% is, we have to find the 100%. This will lead us to have to cross multiply using the following formula.
[tex] \frac{144}{x} = \frac{60}{100} [/tex]
x is representing the 100% and is what we have to find, and to find it we cross multiply 60 and x, and 144 and 100.
[tex]60x = 14400[/tex]
then, we will need to divide 14400 by 60 to have the x by itself.
[tex]x = 14400 \div 60[/tex]
[tex]x = 240[/tex]
