Question

The ratio of adults to kids in a park is 2:3. If there are 12 adults in the park, how many total people are in the park?

Answer 1

2/3 = 12/X

1/3 = 6/X

X = 3(6) = 18 children in the park

add 12 adults for grand total 18+12 = 30 people

or you could have done the ratio of 2/(2+3) = 2/5 = 12/T

2T = 60 (cross multiply)

divide by 2

T = 60/3 = 20 Total people

1st way was use the ratio as given, adults;children

way is use the ratio of adults/total people
