QuestionSolve mentally. (NO WORK TO SHOW) A color called Passion Pink is made by mixing red paint and white paint in a ratio of 2 to 7 . How many drops of white paint do you need:
S If you use 20 drops of red paint? L If you use 40 drops of red paint? T If you use 3 drops of red paint?

Studdy Solution
Calculate the drops of white paint for 3 drops of red paint.
Using the ratio 2:7: $\frac{7 \text{ drops of white paint}}{2 \text{ drops of red paint}} = \frac{x \text{ drops of white paint}}{3 \text{ drops of red paint}}$
Solving for $x$: $x = \frac{7}{2} \times 3 = 10.5 \text{ drops of white paint}$
The solutions are: S = 70 drops of white paint, L = 140 drops of white paint, T = 10.5 drops of white paint.
