Compare two fractions with different numerators and different denominators (e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2). Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols >, =, or <, and justify the conclusions (e.g., by using a visual fraction model).
You order 4 pizzas for a party. At the end of the party only half of a pizza is left. How much pizza did the guests eat? That's one problem can't think of a 2nd one.
