Answer:
The stack of 10 pennies is 0.08 inches taller than a stack of 10 dimes.
Explanation:
A stack of 100 pennies is 6.1 inches tall and a stack of 100 dimes is 5.3 inches tall . From the initial statement we can conclude a stack of pennies is taller than same number of stack of dimes.
The question asked us to find how much taller a stack of 10 pennies than a stack of 10 dimes.
Firstly, the stack of 10 pennies height and the stack of 10 dimes height need to be calculated before knowing how much taller through the difference.
since stacked 100 pennies is 6.1 inches
stacked 10 pennies = ?
cross multiply
height of stacked 10 pennies = (10 × 6.1)/100
height of stacked 10 pennies = 61/100
height of stacked 10 pennies = 0.61 inches
since stacked 100 dimes is 5.3 inches
stacked 10 dimes = ?
cross multiply
height of stacked 10 dimes = (10 × 5.3)/100
height of stacked 10 dimes = 53/100
height of stacked 10 dimes = 0.53 inches
The difference in height is 0.61 - 0.53 = 0.08 inches
