Question:
Jenny is making tie-dyed shirts for her class with her school colors, blue and yellow. She used a total of 8 ounces of fabric paint. The amount of blue paint is 3 times the amount of yellow paint. Make a diagram to show the ratio of blue paint to yellow paint
Answer:
The ratio of blue paint to yellow paint is 3 : 1
Solution:
Let "x" be the amount of blue paint in ounces
Let "y" be the amount of yellow paint in ounces
She used a total of 8 ounces of fabric paint
Therefore,
x + y = 8 -------- eqn 1
The amount of blue paint is 3 times the amount of yellow paint
Amount of blue paint = 3 times the amount of yellow paint
x = 3y ------- eqn 2
Substitute eqn 2 in eqn 1
3y + y = 8
4y = 8
Divide both sides by 4
y = 2
Substitute y = 2 in eqn 2
x = 3(2)
x = 6
Therefore , the amount of blue paint is 6 ounces and the amount of yellow paint is 2 ounces
Find the ratio
To find out the ratio of blue paint to yellow paint, divide the amount of blue paint by the amount of yellow paint

Which means, of every 4 parts of paint, three parts are blue and one part is yellow
