Convert Decimal into Percentage

To converting decimal into percentage, simply multiply by 100 and add percent sign %.

Example: convert 0.45 into percent.

Solution: to convert 0.45 into percent we multiply o.45 by 100,

                       we get  0.45 x 100

                             = (45/100)x100

                               = 45%

Example: convert 0.53 into percent.

Solution: to convert 0.53 into percent we multiply 0.53 by 100,

                       we get  0.53 x 100

                             = (53/100)x100

                               = 53%

Example: convert 0.09 into percent.

Solution: to convert 0.09 into percent we multiply 0.09 by 100,

                       we get  0.09 x 100

                             = (9/100)x100

                               = 9%
Example: convert 0.675 into percent.

Solution: to convert 0.675 into percent we multiply 0.675 by 100,

                       we get  0.675 x 100

                             = (675/1000)x100

                               = 67.5%

Example: Find 22% of 120

                          = (22 x 120)/100

                          = 26.4

Example: Find 25% of 500

                             = (25 x 500)/100

                             = 125

Example: Find 30% of 1500

                            = (30 x 1500)/100

                            = 45000/100

                            = 450

Example: John’s monthly income is $1500, he spent $500 per month on clothes. find the percent of monthly income saved by john. 

Solution:   John’s monthly income = $1500

              john’s saving per month = $1500 – $500

              john’s saving per month = $1000

percent of saving income = (1000/1500)x100

                                     = 1000/15

      percent of saving income = 66.6%

Example: In a village 35% are females, 50% males and remaining are children, find the percent of children?

Solution: Given percentage are females = 35%

                         percentage are males = 50%

Total percentage of females and males = 35 + 50

Total percentage of females and males = 85

percentage of children = 

total percentage – percentage of females and males 

                               = 100 – 85

               percentage of children = 15% 

                 Hence 15% are children.
