Answer:
see the explanation
Step-by-step explanation:
we know that
An extended ratio compares three or more numbers.
In the extended ratio a:b:c
The ratio of the first two numbers is a:b (you can write a to b or a/b)
The ratio of the last two numbers is b:c (you can write b to c or b/c)
The ratio of the first and last numbers are a:c (you can write a to c or a/c)
The third one tells us the price is $12 per liter, that is to say, the top number is twelve times the bottom number.
.25 × 12 = $3
.7 × 12 = $8.40
2.5 × 12 = $30
3.52 × 12 = $42.24
$57.60 / 12 = 4.80 liters
