17. 17. Why is understanding percent important? <ul><li>You will know the relationship between any number and 100 as a percent . </li></ul><ul><li>You will know how a percent translates into fractions . </li></ul><ul><li>What are other reasons why it is important to know how to understand </li></ul>IMP
18. 18. What is the Percentage ? If 24 out of 100 units are shaded blue. GP = __ % _24_ 100
