Ada buys 3 pounds 8 ounces of ham and 4 pounds 2 ounces of cheese for a party. How much ham and cheese did she buy?
A. 5 pounds 12 ounces or 5three-fourths pounds
B. 7 pounds 9 ounces
C. 7 pounds 10 ounces or 7five-eighths pounds
D. 8 pounds
To add up the weight of the ham and cheese, we need to convert the ounces to pounds first.
3 pounds 8 ounces = 3.5 pounds
4 pounds 2 ounces = 4.125 pounds (since 1 pound = 16 ounces, 2 ounces is 2/16 = 0.125 pounds)
Adding these up, we get:
3.5 + 4.125 = 7.625 pounds
Therefore, Ada bought 7 pounds 10 ounces or 7five-eighths pounds of ham and cheese.
So the answer is C. 7 pounds 10 ounces or 7five-eighths pounds.
