                  7     x 100%=  28 %
                  25

                  Example

                  Convert each part of the ratio to percentage: 1:2:5


















                  Example

                  Convert given percent into decimal fractions:

                  25%

                  Ans- 25%  =   25    = 0.25

                    Finding new number, when there is increase in percentage.

                  New number = original number + (increase in percentage × number)

                  Example 1: The Cost of a mobile phone  is Rs 15,000. Find the new price if there is a
                  increase of 5%

                  New price = original price + 5% of original price

                  New price = 15,000+    5   ×15,000
                                        100

                  New price = 15,000+750 = 15,750

                  Here Rs 750 is increase in the price.

                    Finding new number, when there is decrease in percentage.

                                                                2
