Here are the step-by-step calculations for each problem on the worksheet.
Conversion Factors to Remember:
* 1 kilogram (kg) = 2.2 pounds (lbs)
* 1 pound (lb) = 16 ounces (oz)
* 1 kilogram (kg) = 1000 grams (g)
Calculations:
a.) 23 lbs. = _______ kg

* Round to the nearest hundredth:
14.55 kg
e.) 4 lbs. 5 oz. = _______ kg
* Convert 5 oz to lbs: $5 \div 16 = 0.3125$ lbs.
* Total lbs: $4.3125$ lbs.
* Convert to kg: $4.3125 \div 2.2 = 1.9602...$
* Round to the nearest hundredth:
1.96 kg
f.) 75 lbs. = _______ kg
* Divide by 2.2: $75 \div 2.2 = 34.0909...$
* Round to the nearest hundredth:
34.09 kg
g.) 10 ½ lbs = _______ kg
* Convert fraction to decimal: $10.5$ lbs.
* Divide by 2.2: $10.5 \div 2.2 = 4.7727...$
* Round to the nearest hundredth:
4.77 kg
h.) 1000 grams = _______ kg

* Then convert kg to lbs: $4 \times 2.2 =$
8.8 lbs.
m.) 2000 grams = _______ lbs.
* First, convert grams to kg: $2000 \div 1000 = 2$ kg.
* Then convert kg to lbs: $2 \times 2.2 =$
4.4 lbs.
n.) 16.5 kg = _______ lbs.
* Multiply kg by 2.2: $16.5 \times 2.2 =$
36.3 lbs.
o.) 35 kg = _______ lbs
* Multiply kg by 2.2: $35 \times 2.2 =$
77 lbs
p.) 47.5 kg = _______ lbs.
* Multiply kg by 2.2: $47.5 \times 2.2 =$
104.5 lbs.
q.) 55 kg = _______ lbs.
* Multiply kg by 2.2: $55 \times 2.2 =$
121 lbs.
r.) 3000 grams = _______ kg
* Divide grams by 1000: $3000 \div 1000 =$
3 kg
s.) 5000 grams = _______ lbs.
* First, convert grams to kg: $5000 \div 1000 = 5$ kg.
* Then convert kg to lbs: $5 \times 2.2 =$
11 lbs.
t.) 6000 grams = _______ kg.
* Divide grams by 1000: $6000 \div 1000 =$
6 kg.
u.) 7500 grams = _______ kg. = _______ lbs.
* First, convert grams to kg: $7500 \div 1000 =$
7.5 kg.
* Then convert kg to lbs: $7.5 \times 2.2 =$
16.5 lbs.
