Answer:
You need to add 12 pint of yellow.
Step-by-step explanation:
This is the method I used:
There is 4 pint of Yellow (Y) and 4 pint of Blue (B)
because they said is in equal amounts, so they are 50% each.
We need 80% Y and 20% B
so 4:20 = x=80 (4 pints is 20% as "how many pints" is 80%)
So x = 16
We already have 4 pint of Yellow, so we need more 12.
6.4 pint of yellow paint we need to add to the mixture.
"A percentage is a number or ratio that can be expressed as a fraction of 100."
"It is a statement which consists of equal symbol between two mathematical expressions."
For given example,
8 pint mixture of paint that is made up of equal amounts of yellow paint and blue paint.
Let we need 'x' amount of yellow paint.
To create a certain shade of green, you need a paint mixture that is 80% yellow.
So, we get an equation [tex]\frac{x}{8}\times 100 =80[/tex]
We solve above equation.
[tex]\Rightarrow \frac{x}{8}\times 100 =80\\\\\Rightarrow \frac{x}{8} = \frac{80}{100}\\\\ \Rightarrow x = 0.8\times 8\\\\\Rightarrow x = 6.4~~pints[/tex]
Therefore, 6.4 pint of yellow paint we need to add to the mixture.
