Answer:
[tex]0.40\ \text{Pounds}[/tex]
Step-by-step explanation:
The mass of pepperoni placed on the scale is
[tex]\dfrac{4}{10}\ \text{pounds}[/tex]
[tex]=0.4\ \text{Pounds}[/tex]
The hundredths place means 2 digits after the decimal point.
Trailing zeros after the decimal point do not change the value of the number.
So, here the scales will show [tex]0.40\ \text{Pounds}[/tex].
