Answer
The original statement is true. A 10-pound object weighs more than a 4-kilogram object.
Work Step by Step
$1~lb \approx 0.45~kg$
We can convert 10 pounds to units of kilograms.
$10~lb = \frac{10~lb}{1}\times \frac{0.45~kg}{1~lb}$
$10~lb = 4.5~kg$
We can see that the original statement is true. A 10-pound object weighs more than a 4-kilogram object.
