Step 1 :Given that the percent formula is $A=P B$, where $A$ is $P$ percent of $B$.
Step 2 :We are asked to find what is $19 \%$ of 30.
Step 3 :Here, $P$ is 19 and $B$ is 30. We need to find $A$, which is $P$ percent of $B$.
Step 4 :Substitute $P$ and $B$ into the formula, we get $A = 19 \times 30$
Step 5 :Calculate $A$ to get the final answer.
Step 6 :Final Answer: $19 \%$ of 30 is \(\boxed{5.7}\)
