Answer:
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
