Given
Roast beef = 1 pound and 11 ounces
Corned beef = 2 pounds and 5 ounces
Find how much more corned beef did Marsha buy than roast beef.
Solution
First, convert pounds to ounces
1 pounds = 16 ounces
2 pounds = 32 ounces
Roast Beef 16 ounces + 11 ounces = 27 ounces
Corned Beef 32 ounces + 5 ounces = 37 ounces
37 - 27 = 10 ounces
The answer is 10 ounces
