To find out how many tablespoons of white paint are needed if there are 8 tablespoons of red paint, we can set up a proportion using the given ratio.
Given ratio: 4 tablespoons of red paint to 3 tablespoons of white paint
Let x be the number of tablespoons of white paint needed.
4/3 = 8/x
Cross-multiply and solve for x:
4x = 8*3
4x = 24
x = 24/4
x = 6
Therefore, 6 tablespoons of white paint are needed if there are 8 tablespoons of red paint.
To find out how many tablespoons of red paint are needed if there are 12 tablespoons of white paint, we can set up a proportion using the given ratio.
Given ratio: 4 tablespoons of red paint to 3 tablespoons of white paint
Let y be the number of tablespoons of red paint needed.
4/3 = y/12
Cross-multiply and solve for y:
4*12 = 3y
48 = 3y
y = 48/3
y = 16
Therefore, 16 tablespoons of red paint are needed if there are 12 tablespoons of white paint.
