Holly ordered 3 pounds and 11 ounces of roast beef and 4 pounds and 10 ounces of ham. How much meat did Holly order?

What do you think?

add the pounds then add the ounces

Right.

After you've done that, you'll need to convert the 21 ounces to 1 pound and 5 ounces.

1 pound = 16 ounces

To find out how much meat Holly ordered, we need to first convert the weights of roast beef and ham to a common unit of measurement. In this case, we can convert both weights to ounces and then add them together.

For roast beef:
3 pounds = 3 * 16 ounces = 48 ounces
11 ounces = 11 ounces

Total weight of roast beef = 48 ounces + 11 ounces = 59 ounces

For ham:
4 pounds = 4 * 16 ounces = 64 ounces
10 ounces = 10 ounces

Total weight of ham = 64 ounces + 10 ounces = 74 ounces

Finally, to find out how much meat Holly ordered, we add the weights of roast beef and ham:
59 ounces + 74 ounces = 133 ounces

Therefore, Holly ordered a total of 133 ounces of meat.
