There are twice as many centipedes as humans on a certain island and half as many sheep as humans. How many sheep and humans in total are on the island if the number of centipedes is 100?
How many humans are on the island? ** The number of humans on the island is 100 / 2 = <<100/2=50>>50.
How many sheep are on the island? ** There are 1/2 * 50 = <<1/2*50=25>>25 sheep on the island.
How many sheep and humans are on the island? ** The total number of sheep and humans is 25 + 50 = <<25+50=75>>75.
