Step-by-step explanation:
<em>The given information is</em>
- 6 parts of yellow paint with 3 parts of blue paints to make green paint
- The yellow paint adds by 1 part
We need to find the ratio of yellow to blue
<em>Let us find the correct answer</em>
∵ The yellow = 6 parts
∵ The yellow adds by 1 part
∴ The yellow = 6 parts + 1 parts = 7 parts
∵ The blue = 3 parts

∴ The ratio of yellow to blue = 
The new ratio is
150 + 15x = 400
(-150) 150 + 15x = 400 (-150)
15x = 250
(/15) 15x = 250 (/15)
x = 16.67
