Each dandelion produces 300 seeds. 1/3rd of the seeds land in water and die. 1/6 of the starting number are eaten by insects. Half the remainder sprout and are immediately eaten. How many dandelions survive long enough to flower?

How many seeds land in water? ** First find the number of seeds that land in water: 300 seeds * 1/3 = <<300*1/3=100>>100 seeds
How many seeds are eaten? ** Then find the number of seeds that are eaten: 300 seeds * 1/6 = <<300*1/6=50>>50 seeds
How many seeds remain? ** Subtract the number of seeds that are destroyed to find the number that sprout: 300 seeds - 100 seeds - 50 seeds = <<300-100-50=150>>150 seeds
How many seeds survive? ** Then divide that number by 2 to find the number of sprouts that survive: 150 seeds / 2 = <<150/2=75>>75 seeds
