Work out the percent of the number.
50% of 80 =
This exercise practises finding a common percent of a whole number — without a calculator. The numbers are chosen so the answer is always a whole number. Use the friendly tricks: 10 % is one tenth, 50 % is half, 25 % is a quarter.
What does this generator do?
Picks a friendly percent (10, 20, 25, 50 or 75) and a number whose answer is a whole number, then asks you to work it out.
How to use it
10 % = divide by 10. 50 % = halve. 25 % = halve and halve again. 75 % = three quarters (half plus half-of-half). 20 % = divide by 5.
