17. To obtain a certain shade of paint, Denise mixed 2 1/8 gallons of red paint with 1 1/4 gallons of black paint and 1 1/2 gallons of yellow paint. How much paint did he have?
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
17. To obtain a certain shade of paint, Denise mixed 2 1/8 gallons of red paint with 1 1/4 gallons of black paint and 1 1/2 gallons of yellow paint. How much paint did he have?
Given that to obtain a shade of a paint denise mixed 2 (1/8) gallons of red paint with 1 (1/14) gallons of black paint and 1 (1/12) gallons of yellow paint.
Here different volumes of three paints are mixed to form a new paint. So we can say that the sum of voumes of three paints is nothing but the volume of the new shade of paint.
Here the volumes of paints are given as mixed fractions so we write them as proper fractions.
Volume of red paint = 2 (1/8) gallons = 17/8 gallons.
Volume of black paint = 1 (1/14) gallons = 15/14 gallons
Volume of yellow paint = 1 (1/2) gallons = 3/2 gallons.
