From the information given
1 pound = 0.45kg
Recall that 1 kg = 1000 gram
0.45 kg = 0.45 x 1000 = 450g
Hence, 1 pound = 450g ----------------------------------(1)
There are 16 Oz in a pound.
This means 1 pound = 16 Oz------------------------------(2)
Since 1 pound = 450g
and 1 pound = 16 Oz
It implies 450g = 16 Oz
Divide both sides by 16
[tex]\begin{gathered} \frac{450g}{16}=\frac{16\text{ Oz}}{16} \\ 28.125g=\text{ 1 Oz} \\ \text{Hence, 1 Oz = 28.125g} \\ \text{ The answer is 28.125g} \end{gathered}[/tex]
