A park takes up 150 acres of land. Each country takes up 1/5 of the park's land. The roller coasters take up 4/15 acres of each country's land. How much of each country's land is not taken by roller coasters?

Answer 1

22 acres

Answer 2

150/5 = 30 acres per country.
4/15 acres are taken up by the roller coasters. So 30/15= 2 acres is 1/15 Therefore 4/15 = 8 acres for each roller coaster.
How much of each country's land is not taken by roller coasters? 22 acres.
30 - 8 = 22
