The question
920 lb = ________ oz
20 lb = ? oz
lb → ozsmaller unit, bigger number
1 lb =16 oz
20 × 16 =320
320 oz
- One oz is smaller than one lb, and it takes MORE of a small thing to make the same amount. So the number has to get bigger — which means multiplying.
- There are 16 oz in one lb, so that is the number to multiply by.
- 20 × 16 = 320, so 20 lb is 320 oz. Check the direction held: the number got bigger, which is what a smaller unit does.
