Question

jen uses 8.2 of blue paint and white paint to paint her bedroom walls. 4/5ths of this amount is blue paint, and the rest is white paint. how many pints of white paint did she use to paint her bedroom walls?

Answer 1

The amount of white paint Jen used to paint the walls in her room is:

• 1.64 pints.

Explanation:

To solve the exercise you only have to pay attention to the statement, in the section that says that 4/5 parts of the total painting is blue, therefore, if 1 is the total painting, you must do a subtraction:

• 1 - 4/5 = 1/5

Since the remaining white paint is 1/5 of the total, you have two ways to solve the exercise: multiply the total paint (8.2 pints) by 1/5 or divide the number by 5, as shown below:

• Amount of white paint = 8.2 pints * (1/5) = 1.64 pints.
• Amount of white paint = 8.2 pints / 5 = 1.64 pints.

As you can see, the two methods provide a value of 1.64 pints, which corresponds to 1/5 of the total paint and is the amount of white paint used.
