Math Help

So I’m doing this word problem with Sam. I have the answer but I don’t
know WHY it is the answer. Can any of you out there in cyberspace
help?
Here is the question:
Sarim has $1 in coins. One-fifth of the coins are dimes,
two-fifteenths are nickels, and two-thirds are pennies. Tell how many
of each coin he has.
The answer:
6 dimes; 4 nickels; 20 pennies; making 30 coins
Now that makes sense because all the fractions work into the total
number of coins nicely. (i.e. 1/5 of 30 is 6… pennies) But how would
I have attacked this problem and more importantly (to me) why would I
do it that way…
Anyone?
