78 children attended a trip to Six Flags. 60 of them were boys. Find the ratio of the number of boys to girls, and express the number of boys to the number of girls--remember to express the ratio in lowest terms. (3 points)
First we need to find out how many girls there were Subtract the number of boys from the total 78 - 60 = 18 girls Boys : Girls 60 : 18 The GCF of all these numbers is 6, therefore we divide both sides by 6 to get the simplified ratio 60/6 = 10 18/6 = 3 10:3
