Answer:
Henry will need 6 pints of red color.
All together he will need 15 pints.
Step-by-step explanation:
Henry needs 2 pints of red paint and 3 pints of yellow paint to get a specific shade of orange.
The ratio is 2:3
Now he uses 9 pints of yellow paint so we need to find the pins of red paint used to get the same orange.
Let the pints of red paint be x
We can relate this as:
Solving for x;
So, x = 6
Hence, 6 pints of red color are needed.
And all together Henry needs pints of paint.
