Question

a shade of orange paint is made with 5 parts red paint and 15 parts yellow paint what percent of the paint is red and what is the simplified ratio of yellow paint?

Answer 1

Part A) To find what percent of the paint is red, you divide the part (5) by the whole (15 + 5 = 20)

Answer: 5/20 = 25%

Part B) To simplify the 15:5 ratio of yellow paint to red paint, you determine what number both 5 and 15 is divisible by. Both 5 and 15 are divisible by 5.

15/5 = 3 and 5/5 = 1   Therefore, the simplified ratio is 3/1 or 3:1 (read as 3 to 1)
