Answer:
In order
12
60
120
Explanation:
This is a ratio problem.
It takes 6 quarts of red paint for mixing with 5 quarts of yellow paint to produce orange paint. The ratio of red/yellow is 6/5
If we double the quantity of yellow paint from 5 to 10 in the second case, the quantity of red paint will also double from 6 to 12 (first box)
In the 3rd case, the quantity of yellow paint is 10 times so quantity of red paint is 6 * 10 =60
In the last case, yellow paint is 20 times the original value of 5 so red paint is also 20 times original value = 6 * 20 = 120
The ratio of red paint to yellow paint is 6/5
So just multiply each value under yellow paint by this ratio to get the quantity of red paint
For example, for yellow paint = 10 quarts, red paint = 10 * 6/5 = 12 and so on
