Final answer:
To find the ratio and express it in its lowest terms, we can set up a proportion with the given measurements and solve for the unknown unit. The ratio of 825ml to 1.5l is approximately 550:1.
Step-by-step explanation:
To find the ratio and express it in its lowest terms, we need to convert the given measurements of 825ml and 1.5l to a common unit. Since there are 1000ml in 1l, we can set up the following proportion:
825ml / 1.5l = x ml / 1000ml
Cross multiplying, we get:
825ml * 1000ml = 1.5l * x ml
Simplifying, we have:
825000ml = 1.5l * x ml
Dividing both sides by 1.5l, we find:
x ml = 825000ml / 1.5l
Calculating the value, we get:
x ml ≈ 550000ml
Therefore, the ratio of 825ml to 1.5l is approximately 550000ml to 1000ml, which can be simplified to 550:1.
