๐ Topic Summary
Customary weight is how we measure how heavy things are using units like ounces (oz) and pounds (lb). When solving word problems, it's important to read carefully to understand what the question is asking. Addition problems involve combining weights, while subtraction problems involve finding the difference between weights. Remember that 1 pound equals 16 ounces! ๐ช
For example, if you have a bag of apples weighing 2 pounds and another bag weighing 3 pounds, you can add them together to find the total weight: $2 + 3 = 5$ pounds. If you have a box of chocolates weighing 1 pound and you eat 8 ounces, you'll need to subtract to find how much is left.
