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
[tex]\frac{x}{y} = \frac{6}{2} = \frac{3}{1}[/tex]
Which means, of every 4 parts of paint, three parts are blue and one part is yellow
The diagram is attached below
Answer:
3:1
Step-by-step explanation:
On the blue bar, put 3, and on the yellow bar put 1. Good luck on the next question!
