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.
