Question

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

Answer 1

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
