Work Step by Step

In the “U.S. to Metric Units” side of the table, you see that 1 pound = 0.45 kilogram. Two unit fractions can be written using that information.(1 pound)/(0.45 kilograms) Or(0.45 kg)/(1 pound). Multiply by the unit fraction that allows you to divide out pound (that is, pound is in the denominator). 11 lb *(0.45 kg)/(1 pound). = 4.95 kg = about 5 kg
