3/15 + 2/15 + 10/15 = 15/15 and hence this all the coins Sarim has. Threefifths of the coins are dimes and the number of coins is an integer, hence the number of coins is divisible by 15. Thus the number of coins is 15 or 30 or 45 or 60 ... What if the number of coins is 15?
So with these fractions if the total number of coins is 15 the total value is only fifty cents. What if the number of coins is 30? Penny
