there are 118 ridges around the edge of a dime. key has $5 in dimes. how many ridges,are there in all of kellys dimes combined? please solve. thanks
How many dimes does he have?
Multiply the number of dimes by 118.
To solve this problem, we need to find out how many dimes Kelly has and then calculate the total number of ridges.
First, let's find out how many dimes Kelly has by dividing the total amount of money she has ($5) by the value of each dime (10 cents or $0.10):
Number of dimes = Total amount of money / Value of each dime
Number of dimes = $5 / $0.10 = 50 dimes
Next, we need to calculate the total number of ridges. We know that there are 118 ridges on each dime, so we multiply the number of dimes by the number of ridges per dime:
Total number of ridges = Number of dimes × Number of ridges per dime
Total number of ridges = 50 dimes × 118 ridges = 5900 ridges
Therefore, there are 5,900 ridges in all of Kelly's dimes combined.
