you are looking for a unit rate (for 1 quart of red, how much white is used).
notice all red amounts are less than white, so b and c make no sense.
I look at the 4:20 and think, half of the paint would be 2:10, half of that is 1:5
(you could also start with 4:20 and divide each by 4 to get this answer)
3/4 x n=1......n equals 4/3.
In order for n to equal 1 you have to find a number that will make 3/4 a whole number after you multiply it. Usually in problems like these the answer is usually the fraction but flipped around. So 3/4 and 4/3....when you multiply the numerators you get 12 and when you multiply the denominator you get 12 so 12/12, which equals 1. hope that makes sense.

Answer:
$38.25
Step-by-step explanation:
Perimeter of a rectangle = 2W + 2L
(where W is the width and L is the length)
Given:
- width = 2.5 yd
- length = 6 yd
⇒ perimeter = (2 x 2.5) + (2 x 6)
= 5 + 12
= 17 yd
Given:
- cost of fence = $2.25 per foot
⇒ total cost = 17 x 2.25
= $38.25
