You have prepared 42 ml of distilled water,18 ml of vinegar and 47 ml of salt water for an experiment.
how many milliliters of solution will you have if you first pour the distilled water, then the salt water, and finally the vinegar into your beaker

i’ll just s take the points thxs

why are you giving so many marks make your marks less and make a question list so that i can understand your question very nicely

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.

your answer is

a.
