This fun word problem will give elementary level students the opportunity to practice skills such as fractions and decimals. Don’t be afraid to dip your toe in the water, take a look at the question below and see if you can work out the solution. 


Question: Luke says he saw a piranha that was 4¾ inches long. Howard says he saw a piranha that was 4.7 inches long. Who saw the bigger piranha?

Take your time and think it over. When you're ready, look below to compare your solution to ours.

 

Solution: One way to solve this problem is to write both measurements as decimals. Since ¼ is equal to 0.25, ¾ must be equal to 0.25 + 0.25 + 0.25 = 0.75. That means that a piranha that is 4¾ inches long is 4.75 inches long. Since 4.75 is greater than 4.7, Luke saw the bigger piranha.
