CONVERSION FROM FRACTION TO PERCENTAGE

CONVERTING FROM FRACTION TO PERCENTAGE 

For conversion from fraction to percentage, we have to calculate the ‘Denominator’ of ant fraction to be converted into 100 first, then on basis of 100 as ‘Denominator’, we can find the number percentage.

 

1)  5/20 = ? %

Step.1)  First observe the ‘Denominator’ of the given fraction which number table may bring 100 in ‘Denominator’ in next step of the calculation. In given fraction 20 has given, so we would like to recall the table of 20 and we can  find 20 x 5 = 100, 5 is the ‘Multiplier’ here.

Step.2)  If 5 is the ‘Multiplier’ for ‘Denominator’ then the same ‘Multiplier’ 5 should be taken for multiplication for ‘ Numerator’ of the same fraction. So, 5 x 5 = 25.

Step.3) So, the fraction should be   25 / 100 =  25%       (Ans.)



2)  13/10 = ? %

Step.1)  First observe the ‘Denominator’ of the given fraction which number table may bring 100 in ‘Denominator’ in the next step of the calculation. In the given fraction 10 is ‘Denominator’, so we would like to recall the table of 10 and we can find 10 x 10 = 100, 10 is the ‘Multiplier’ here.

Step.2)  If 10 is the ‘Multiplier’ for ‘Denominator’ then the same ‘Multiplier’ 10 should be taken for multiplication for ‘Numerator’ of the same fraction. So, 13 x 10 = 130

Step.3) So, the fraction should be   130 / 100 =  130 %      (Ans.)
