Both approaches yield the same result, so there are 87 dimes in $8.70.
To determine the number of dimes in $8.70, we can use two different approaches:
Approach 1: Division
1 dime = $0.10
To find the number of dimes, divide the total amount by the value of one dime:
Number of dimes = $8.70 / $0.10
Number of dimes = 87 dimes
Approach 2: Counting by 10 cent
$8.70 is equivalent to 870 cents (since 1 dollar = 100 cents).
Since each dime is worth 10 cents, we can find the number of dimes by dividing the total cents by 10:
Number of dimes = 870 cents / 10 cents
Number of dimes = 87 dimes
Both approaches yield the same result, so there are 87 dimes in $8.70.
