I need some help to to solve each proportion - I want to be able to explain to my son how to do this properly. The math problem is- 4 over 6 = blank over 21 ?

Answer

The missing value is -14

Step-by-step explanation:

First you make a ratio or proportion: -4/6=x/21

Then you cross multiply

-4x21 which is -84 then 6 times x which is 6x  then the equation becomes 6x=-84

       from 6x you divide which becomes x=-84/6 which is -14
