There were 200 parties in a concert there were4 times as many girls than boys how many girls were there how many more girls than boys

200 = 4b (4 times the amount of boys) + b (the amount of boys)

200 = 5b divide both sides by 5

40 = b

So we have worked out that there is 40 boys so in order to get the number of girls we need to multiply it by 4 which equals 160.

Boys = 40

Girls = 160

120 more girls than boys
