We know 1 dime = 10 pennies or 10 cents
We need to find what number of dimes is equal to 290 pennies
Let the number of dimes be x
10 times Number of dimes = 290
10 * x = 290
Divide by 10 on both sides
[tex]\frac{10x}{10} = \frac{290}{10}[/tex]
x = 29
The number of dimes = 29
29 dimes are equal to 290 pennies because 29 * 10 = 290 pennies
