Try using this method: If we are finding 50% of a number, we know that 50% is the same as a . So all we need to do is work out what half of the number is and we can do this by dividing by ‘2’ (which is the denominator of ). For example: If we are trying to find 50% of 16, we divide 16 by 2 which gives us 8. So 50% of 16 is 8.

Try using this method: If we are finding 10% of a number, we know that 10% is the same as a . So all we need to do is work out what a tenth of the number is and we can do this by dividing by ‘10’ (which is the denominator of ).
