what is the 0.05% of 234.11

Converting .0005% to a decimal - .0005 -  we have

$${\mathtt{0.000\: \!5}}{\mathtt{\,\times\,}}{\mathtt{234.11}} = {\mathtt{0.117\: \!055}}$$

To take the percentage of something, you must first change the percent into a decimal. To do that, you must move the decimal two places to the left. Making 0.05% into 0.0005

Multiply the new decimal by the number you want to find the percentage of.

0.117 is your answer.
