The deli scale weighs meat and cheese in hundredths of a pound. Sam put 4 10 pound of pepperoni on the deli scale. What weight d

Andreas93 [3]

Answer:

$0.40\ \text{Pounds}$

Step-by-step explanation:

The mass of pepperoni placed on the scale is

$\dfrac{4}{10}\ \text{pounds}$

$=0.4\ \text{Pounds}$

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 $0.40\ \text{Pounds}$ .
