To find the ratio of red to blue in the purple paint mixture, you can compare the amounts of red and blue directly.
You have:
- Red = 24 oz
- Blue = 28 oz
The ratio can be represented as:
\[ \text{Ratio of Red to Blue} = \frac{\text{Red}}{\text{Blue}} = \frac{24}{28} \]
To simplify this ratio, divide both the numerator and the denominator by their greatest common divisor (GCD). The GCD of 24 and 28 is 4.
\[ \frac{24 \div 4}{28 \div 4} = \frac{6}{7} \]
Thus, the simplified ratio of red to blue is 6:7.
