Today is the explanation for yesterday’s Arithmetic Reasoning problem on percentages.  This is a  topic I cover in my ASVAB prep course.  As one who tutors for the ASVAB, I know the importance of teaching percentages to my students to help improve their ASVAB math scores.  In this example to figure out what percentage 1/8 is, I teach my students to set up a  proportion.

1/8 = x/100

Cross multiply and solve.

8x = 100

x = 12.5%

Did you know how to solve this problem?
