We are asked to find 7 is what percent to 30.
We will use proportions to solve our given problem.
Let us assume that 7 is n% of 30. So we can set a proportion as:
[tex]\frac{n}{100}=\frac{7}{30}[/tex]
Let us solve for n.
[tex]\frac{n}{100}\cdot 100=\frac{7}{30}\cdot 100[/tex]
[tex]n=\frac{7}{3}\cdot 10[/tex]
[tex]n=\frac{70}{3}[/tex]
[tex]n=23.333[/tex]
Therefore, 7 is [tex]23.333\%[/tex] of 30.
