3 percent of 420 is what ?
Alenkasestr [34]
Hi there! The answer is 12.6


First we need to change the percentage into a decimal. To convert this percentage, we have to divide it by 100.

3\% = 0.03


Hence, to find 3 percent of 420, we must multiply 420 by 0.03. We get the following:

3\% \times 420 = 0.03 \times 420 = 12.6
