Question

There are 12,000 people at a BTS concert. The ratio of children to adults is 2 to 4. Exactly how many more adults are there than children at the concert? Explain your answer

Answer 1

C/A = 2/4 = 1/2, twice as many adults as children

A=2C

A+C = 12,000

2C + C = 12,000

3C = 12,000

C = 12,000/3 = 4,000

A= 2C = 8,000

A-C = 8,000-4,000 = 4,000 more adults than children

Answer 2

ratio is 2 to 4, which reduces to 1 to 2

if number of children is x, number of adults is 2x

x + 2x = 12000

3x = 12000

x = 4000 children

2x = 8000 adults

4000 more adults than children.
