Answer:
Step-by-step explanation:
If this question is 12 is 30% of what number then you would solve it as such:
[tex]\frac{30}{100} = \frac{12}{x}[/tex]
Note that you can rewrite any percent as the value that they give you over 100, and also since the question says that 12 IS 30% then 12 should be directly across 30% in the proportion itself (as shown above).
This gives:
30x = 1200
Dividing by 30 gives us that
x = 40
So 12 is 30% of 40.
