Step-by-step explanation:
To find the number of pints of red and blue paint needed to make different shades of purple paint, we need to use the given ratios.
Purple #1 is made by mixing red and blue in a ratio of 1:2. So, if we start with 1 pint of red paint, we would need 2 pints of blue paint.
Purple #2 is made by mixing red and blue in a ratio of 1:3. So, if we start with 1 pint of red paint, we would need 3 pints of blue paint.
