### Conversion between the Units of Weight

To Convert larger unit to smaller unit we **multiply**.

To convert smaller unit to larger unit we **divide**.

Observe the image carefully and try to solve the questions based on conversion between the units of weight.

1. **8 lb. = _____ oz.**

**Solu****tion: **

1 lb. = 16 oz

So, 8 lb. = 8 × 16 = **128 oz**

2. **12 ****½ lb.**** = _____oz.**

**Solution: **

1 lb. = 16 oz

So, 12 ½ lb. = 12 ½ × 16 oz** = 200 oz**

3. **64 oz = _____lb.**

**Solution: **

1 lb. = 16 oz, So 1 oz = 1/16 lb.

Now, 64 oz = 1 ÷ 16 × 64

**= 4 lb.**

### Real life applications based on units on Weight (Word Problems)

**Example: **Mrs. Mary handed out 4 ounces of peanuts to each of her 20 students. How many pounds of peanuts did Mrs. Mary hand out?

**Solution:** Peanuts of almonds handed out to 1 student is 4 ounces.

Total no. of ounces of peanuts handed out for 20 students is

= 4 × 20

**= 80 ounces **

**Convert ounces into pounds. **

= 80 ÷ 16 pounds

**= 5 pounds **

So, **Mrs. Mary handed out 5 pounds of peanu**ts
