Answer:
- Darcy bought more Hamburgers than Cheese
- 1/2 pound of cheese < 5/6 pounds of Hamburgers
Step-by-step explanation:
Darcy bought 1/2 pounds of cheese and 5/6 pounds of hamburgers.
Convert these to decimals to be sure which is larger:
= 1/2 = 5/6
= 0.5 pounds = 0.83 pounds
The hamburgers are therefore more so the comparison would look like:
1/2 pound of cheese < 5/6 pounds of hamburgers
