Word Problem Wednesday: How Long is a Goldfish?

May 31, 2017 | Diamond Bar


There’s something fishy about this week’s word problem—jump on in and give it a try (the water’s fine)! 

Terry has a goldfish that is 3¼ inches long. Margot has a goldfish that is 3.3 inches long. Who has the bigger goldfish?

Take a minute to work it out... 


Solution: To solve this problem, we can convert 3¼ to a decimal. A fourth is equal to 0.25, so Terry’s fish is 3.25 inches long. That means that Margot’s fish is bigger because 3.3 is more than 3.25.


Fun Fact: The world's longest goldfish measures 18.7 inches from snout to tail-fin end. That’s almost as long as the average newborn baby!
