Final answer:
To calculate Omar's weight in ounces, you multiply the number of pounds (8) by 16, the conversion factor for pounds to ounces, and then add the remaining ounces (3) to get a total of 131 ounces.
Step-by-step explanation:
The question asks to convert a weight given in pounds and ounces into just ounces. To find out how many ounces Omar weighs, we start by remembering that there are 16 ounces in 1 pound. Since Omar is born weighing 8 pounds 3 ounces, we need to convert those 8 pounds into ounces and then add the extra 3 ounces.
Multiplication is required to convert a larger unit (pounds) to a smaller unit (ounces). Therefore, we multiply the number of pounds by 16 to find the total ounces:
8 pounds x 16 ounces/pound = 128 ounces
After calculating the total ounces from the pounds, we then add the remaining ounces:
128 ounces (from the pounds) + 3 ounces = 131 ounces
So, Omar weighs a total of 131 ounces.
