Julian has 80 Facebook friends. 60% are boys and 40% are girls. Boyd has twice as many friends who are girls and has 100 friends total. What percentage of Boyd’s friends are boys?
Julian's number of friends who are girls is .40*80 = <<.40*80=32>>32
Boyd has twice as many friends as Julian who are girls, a total of 2*32 = <<2*32=64>>64
If Boyd has 100 friends, he has 100-64 = <<100-64=36>>36 boys
The percentage of boys in Boyd's Facebook friends is 36/100*100 = <<36/100*100=36>>36
