10. CBQ - Ratio of colours

​Prema​ loves creating new shades of paint. One day, he decided to mix red paint and white paint to make a light pink colour. He found that the perfect shade is formed when the paints are mixed in the ratio \(​3​:​4​\).

 

Based on this situation, answer the following: 

 

1. If Prema uses ​6​ litres of red paint, how many litres of white paint should he add to keep the same ratio?​

​

• 7
• 10
• 9
• 8

 

2. If he prepares ​14​ litres of the mixture, find the quantity of red paint (in litres).

​

• 1
• 3
• 8
• 6

 

3. If he prepares ​14​ litres of the mixture, find the quantity of white paint (in litres).
