Jada has 3 doubloons. She knows that two of them have the same weight and one of them is heavier than the other two. Jada also has a balance which she can use to compare the weights of coins. Explain or show how Jada can use the balance to figure out which doubloon is heavier and which two are the same weight.

She can put one doubloon on one side of the balance and one doubloon on the other side of the balance. If the balance tilts, that tells Jada which doubloon is heavier.

There are two packages of ground beef at the store. One package says it has 1 pound of beef. The second package says it has 0.97 pounds of beef. Jada says that the 1 pound package has more beef. Do you agree with Jada?

Yes, 1>0.971>0.97 and so the 1 pound package has more beef than the 0.97 pound package
