Question

Ok here is a word problem that I don't understand:

There are 420 members in the soccer club. Of these, 3/7 are long-time
members and the rest are new. If 2/3 of the new members are girls, how many new members are boys

Answer 1

No of members =420
New members are 1-3/7=4/7 of total member
Number of new members =420*4/7=240
Number of new girl members =240*2/3=160
     Number of new boy member=240-160=80
 80 members are boys.

Answer 2

Given = There are 420 members in the soccer club.
3/7 are long-time members and the rest are new.
2/3 of the new members are girls.

Now , A.T.Q

New members = 1- 3/7
                       = 7 - 3 / 7
                       = 4/7

Total number of new members =420 × 4/7
                                        = 60 × 4
                                        =240

Number of new girl members =240×2/3
                                              = 80 × 2
                                              =160    

Number of new boy members = Number of new members - number of new girls

Number of new boy members = 240 - 160
                                               = 80.
