Step-by-step explanation:

100%-45%=55%

  According to question 55%=440

then 1%=440/55=8

so,45%=8*45=360

so total number of girls is 360

Answer 2

Answer:

360

Step-by-step explanation:

Let the total no. of boys be = x

No. of girls = 45%

Hence , No. of boys = ( 100 - 45 ) % of x = 55% of x

No. of Boys = 440

Therefore , our equation is

                  55% of x = 440

                  55/100  of x= 440

                  55  of x = 440*100

                   x = 44000/55

                   x = 800

total no. of girls = 45/100 of 800

                         =  360
