Converting a  Percentage into a Fraction or Decimal:

To convert a given percentage into a fraction or decimal

(i) Remove the sign of percentage  and at the same  time divide by 100.

(ii) Reduce the resulting fraction into its lowest terms  or decimal as required.

Example 1. Express each of the following as fraction.

(a) 40%

Sol.  40 % =\frac{40}{100}=\frac{2}{5}

(b) 37.5%

Sol.  37.5 % =\frac{37.5}{100}=\frac{375}{1000}=\frac{3}{8}

Example 2.  Express each of the following as a decimal.

(a)  6\frac{1}{4} %

Sol. 6\frac{1}{4} %=\frac{25}{4} %= \frac{25}{4}\times \frac{1}{100}=\frac{1}{16}=0.0625

(b) 7.5 %

S0l. 7.5%=\frac{7.5}{100}=\frac{75}{1000}=0.075

Converting a Given Fraction or Decimal into Percentage

To convert a given fraction or decimal into percentage , multiply by 100.

Example 1. Convert  2\frac{3}{5}

into percentage.

Sol. 2\frac{3}{5}=\frac{13}{5}=(\frac{13}{5} \times 100)%=260 %

Example 2 . Convert  0.08 into a percentage.

Sol.  0.08=(0.08 x 100) % =(\frac{8}{100}\times 100)%=8%

Finding  the Percentage of a Given Number

To find percentage of a number , convert the given percentage to a fraction and  then multiply the fraction by the given number.

Example : Find 6 % of 400. 

Sol.  6 % of 400= \frac{6}{100}\times 400=24

Convert one Quantity as a Percentage  of the other

Divide the  first quantity by the second one and multiply the result by 100%.

Example 1. Write 20 m as a percentage of 1 km.

Sol.  1 km =1000 m

20 m as a percentage of 1 km= (\frac{20}{1000}\times 100) % = 2%

of a km

Example 2. Express  20 kg  as a percent of  400 kg .

Sol. 20 kg  as a percent of  400 kg  = (\frac{20}{400}\times 100%)= 5 %

km = 12.8 km

Hence option (c) is correct .

(iv) An English test was conducted out of 80 marks. Vani scored 90 %, Tanya scored 85% and Pranoy scored 82.5%. How many marks  did each one score?
