“It takes Bryce 5/9 of an hour to run 3 miles. What is his speed?” Ellie is trying to solve this problem and says she can find Bryce’s speed by calculating 3 x 9/5 even though the expression that matches the problem is 3 5/9. Explain why both of those÷ expressions Ellie mentioned will find Bryce’s speed.

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
