Holly ordered 2 pounds and 9 ounces of roast beef and 3 pounds and 9 ounces of ham. How much meat did Holly order?

2 lbs., 9 oz. + 3 lbs., 9 oz. = 5 lbs., 18 oz. = 6 lbs., 2 oz.

6lbs,2oz

Right.

To find out how much meat Holly ordered, we need to add the weights of the roast beef and ham. However, the given weights are in pounds and ounces, so we need to convert them into a single unit before adding.

First, let's convert the pounds and ounces into ounces. Since there are 16 ounces in a pound, we can calculate the weights as follows:

Roast beef: 2 pounds = 2 * 16 = 32 ounces
9 ounces

Ham: 3 pounds = 3 * 16 = 48 ounces
9 ounces

Now, let's add the weights of the roast beef and ham:

Roast beef: 32 ounces
9 ounces
_______
41 ounces

Ham: 48 ounces
9 ounces
_______
57 ounces

Finally, adding the weights together:

Roast beef: 41 ounces
Ham: 57 ounces
_______
Total: 98 ounces

Therefore, Holly ordered a total of 98 ounces of meat.
