1. a paint store makes lime green paint by mixing 3 parts yellow paint to 1 part blue paint. a clerk mixes 5 parts yellow paint to 2 parts blue paint. did the clerk use the correct ratio of yellow paint to blue paint? explain.

Explanation:

Step1: Find the correct ratio for lime - green paint

The ratio of yellow paint to blue paint for lime - green paint is \(3:1=\frac{3}{1} = 3\).

Step2: Find the ratio for clerk's mixture

The ratio of yellow paint to blue paint for clerk's mixture is \(5:2=\frac{5}{2}=2.5\).

Answer:

No, the clerk did not use the correct ratio. The correct ratio of yellow paint to blue paint for lime - green paint is \(3:1\) (or \(3\) when written as a unit rate). The clerk's ratio of yellow paint to blue paint is \(5:2 = 2.5\), which is not equal to \(3\).
