PLS HELPP. A certain shade of orange paint requires a 12 to 8 ratio of yellow to red paint. to make the same shade of orange paint using 18 gallons of yellow paint, how much red paint would you need... A. 16 gallons B. 24 Gallons C. 8 gallons or D. 12 gallons

D. 12 gallons

Step-by-step explanation:

This is because 12/8 (yellow to red paint) is equivalent to 3/2.

You must find 3/2 = 18/?

18 is divided by 3 and equals 6, meaning '?' divided by 2 should also equal 6. By working backwards (2 × 6), you can identify the missing number.

If 18 ÷ 3 = 6, you must do 2 × 6 to find the gallons of red paint necessary.

Shown work:

3/2 = 18/?          3/2 = 18/?    3/2 = 12/8 = 18/12

18 ÷ 3 = 6          

6 × 3 = 18          6 × 2 = 12        

12 gallons
