Question

To convert 8 kiloliters to liters, the first ratio is 1 kL/1,000 L. To set up the proportion, the second ratio must be _____.

A. 1,000 L/x

B. 8 kL/x

C. x/1,000 L

D. x/8 kL

Answer 1

it would be b. the first ratio is
1kL
----
1000

so you would match up the kL and not know how many regular liters there are.

8kL
-----
x

Answer 2

B.
`(8kL)/(x)`

Explanation:

For 2 ratios to be the same, they have to be equal to one another, in this case, meaning if a part of one of the ratios is unknown, you must be able to solve it by setting the two ratios equal to one another:

`(1kL)/(1000L) =(8kL)/(x)\\x=(8kL)/((1kL)/(1000L)) \\x=8kL*(1000L)/(1kL) \\x=8000L`
