Step-by-step explanation:

Ex: Twelve of the students in the school choir like to sing solos. These 12 students make up 24% of the choir. How many students are in the choir ?

Write a proportion comparing the percent to the ratio of part to whole.

We know that 12 students represent 24%.

Find the multiplication factor.

Since 12 x 2 = 24, find what number times 2 is equal to 100.

Find the denominator.

12/50 = 24/100

(Since 50 · 2 = 100, the denominator is 50)

Hence, there are 50 students in the choir.
