Answer 1

16.8

Explanation:

you get this by taking the ratio of 12:30 and applying it to 42

you get 30 by taking the total of 12 + 18

you then divide 12 / 30 which equals 0.4

you then multiply 0.4 * 42 which gives you 16.8

if you were to solve for the other ratio you would divide 18 / 30

and then take the answer of that, 0.6 and multiply it by 0.6 * 42

then you have the other part of the ratio.
