1 kilogram (kg) of matter is over twice as heavy as 1 pound (lb). The exact rate is 1kg = 2.2046lb, which means that 1lb = (1/2.2046)kg or 0.4536kg.
To cancel out a unit, multiply by a conversion that contains the unit in the denominator. Because 1kg = 2.2046lb, you can multiply by 2.2046lb/1kg without altering the actual value of the expression. You can use a calculator or an online conversion table to find the weight in pounds. 47kg * 2.2046lb/1kg = 103.6162lb In that equation, the kilograms cancel because 1lb*1kg/1kg = 1lb.
You can reverse the equation to check your answer. Multiply 103.6162 by 0.4536 to get approximately 47. Alternatively, use an estimate or benchmark value to see if your answer makes sense. For example, 47 is close to 50. 50 multiplied by 2.2 is 110. Check that your answer is under 110 but still close to that value. 103.6 pounds fits the criteria.
