EXPLANATION:
1.We must know the data that the exercise gives us.
if 4 out of 10 wore spiritual clothing for 500 how many?
we can solve it with a rule of three;so
[tex]\begin{gathered} 4\rightarrow10\text{ } \\ x\rightarrow500 \\ \text{then }we\text{ multiply 4 }by\text{ 500 }and\text{ divide by 10;} \\ \frac{4\times500}{10}\text{ }=200 \\ \text{the the answer is }for\text{ 500 people 200 wear spiritual clothing} \end{gathered}[/tex]
