A stack of 5 pennies weighs 0.0075 kilograms. One kilogram is approximately 2.2 pounds. How many pounds, rounded to the nearest hundredth, does a stack of 100 pennies weigh?

20 stacks of 5 pennies weight 0.33 pounds

Step-by-step explanation:

First, we need to calculate the weight in kilograms of 20 stacks of 5 pennies:

20 stacks= 0.0075*20

20 stacks= 0.15 kg

Now, we can determine the weight in pounds:

1kg = 2.2 pounds

0.15kg = ?

Weight in pounds= (0.15*2.2)/1

Weight in pounds= 0.33 pounds

20 stacks of 5 pennies weight 0.33 pounds
