Question

In a school 4/7 of the students are girls,if there are 549 boys in the school,how many girls will be there

Answer 1

Answer:

Let the number of total students  = x

so ,

     number of total students - number of girls = number of boys

  x - 4x / 7 = 549

  3x / 7 = 549

  x = 549 * 7  / 3

    = 1281

so , number of girls = 1281  - 549

                                = 732

Answer 2

fraction of girls = 4/7

fraction of boys=7-4=3

now we will devide 549 with 3

549÷3=183

now we will add 183 in 549

ans=732
