Whew! With all these interesting octopus number facts, octopuses are the perfect subject for this week’s word problem challenge! You’ll need your elementary school division and multiplication math skills to solve this one. Are you up for the challenge?

Question: A giant pacific octopus weighs 110 pounds. A blue-ringed octopus weighs 4 ounces. How many blue-ringed octopuses weigh the same amount as a giant pacific octopus?

Take your time finding the solution. When you’re ready, look below to check your solution with ours.

Solution: A pound is 16 ounces, so it takes 16 ÷ 4 = 4 blue-ringed octopuses to make up a pound. So, 4 × 110 = 440 blue-ringed octopuses weigh the same as a 110-pound giant pacific octopus.
