When finding fractions of amounts we divide by the denominator and then multiply by the numerator as shown here:


Therefore to find percentages of amounts we can use the same process as we know that we can turn a percentage into a fraction by putting it over 100. So, to find 10% of an amount we are finding 10/100 of an amount. This video should help explain this further:


To find less rounded percentages (e.g. 11%) of amounts we may need to find smaller amounts and then add them together, especially when the fraction can not be simplified. Hopefully this written explanation will demonstrate that:


Now try these:
