Question

Of the 75 teachers at a school, 20 teach math. Around what percent ofthe teachers at the school teach math?

Answer 1

the percent of x out of n is given by

`(x)/(n)*100\text{ \%}`

In this case,

`x=20,n=75`

Therefore,

`(20)/(75)*100\text{ \%}=(4)/(15)*100\text{ \%}=(400)/(15)\text{ \%}=(80)/(3)\text{ }\approx27\text{ \%}`

Hence, the percent of the teachers at the school teach math 27 %
