1/5
If one-fifth of the coins are dimes two fifteeths are nickles and two-thirds are pennies how much of each coin do you have for a total of one dollars worth of coins.
2/3 * 1/5 = 2/15 [in order to compute the answer multiply the numerators of both fractions over the product of the denominators] whenever a problem says "of" it essentially means to multiply. So, in essence two-thirds of one-fifth equals two-fifteenths.
The sum of 2/3 and 1/5 is 13/15.
