A paint mixer calls for 3 parts of white paint to 8 parts of red paint to make pink. How many parts of red paint would you mix with 12 parts of white paint to get the same shade of pink?

32 parts red

Step-by-step explanation:

3 parts white : 8 parts red

12 parts white : ?

12/3 x 8 = 32 parts red

32 parts

Step-by-step explanation:

We can use ratios to solve

3 white           12 white

=

8 red              x red

Using cross products

3x = 8*12

3x = 96

Divide each side by 3

3x/3 =96/3

x= 32

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
