To solve the problem step by step, we will use the concept of direct proportions. ### Step-by-Step Solution: 1. **Understanding the Proportion**: We know that 1 part of red pigment requires 75 mL of base. We need to find out how many parts of red pigment (let's call it X) are needed for 1800 mL of base. 2. **Setting Up the Proportion**: ...
