Math: ounces to pounds and ounces
The tutor shows a conversion from early Math 10 Pre-Calc.
Herein, I use the abbreviations oz for ounce and lb for pound.
Example: Convert 1013 ounces to pounds and ounces.
Solution:
- Realize that 16 oz=1 lb.
- Divide 1013 by 16 to get how many whole pounds you have.
- On a calculator, you’ll get the answer 63.3125. Keep the 63, but discard the decimal.
- The 63 means 63 pounds. You just need to find the number of ounces left over.
- Multiply 63 by 16; you’ll get 1008.
- The number of ounces left over is 1013-1008, or 5 ounces.
- Realize the meaning of the answer: 1013 oz is 63 lb, 5 oz.
- Check your answer: 63×16+5=1013:)
There are other ways to do this conversion, but this way seems the neatest that doesn’t use the fraction button.
I’ll be discussing unit conversions in future posts:)
