Answer:
0.05 oz
Step-by-step explanation:
Usually, the greatest number that is allowed for approximation, assuming that the number itself is obtained by approximation, is the greatest possible error of it.
It is usually half the place value of the last digit of the number.
Here we are given [tex]4\frac{1}{2}[/tex] oz which is equal to [tex]4.5[/tex] oz. The last digit is 5 which is at the tenth place (0.1) so the greatest possible error for this would be its half.
[tex]\frac{0.1}{2}[/tex] = 0.05 oz
