Answer 1

300%

Answer 2

You can use a formula to solve this.
\[\large \large \frac{ is }{ of } = \frac{ Percent }{ 100 }\]
30 goes to the is (Since it has the is next to it)
And 10 goes to the of (Since it has the of next to it)
So your proportion should look like: \[\frac{ 30 }{ 10 } = \frac{ Percent }{ 100 }\] Cross multiply to get 10x = 3000
Divide 10 to get 300%
Make sense?
I hope this help!
