You can do this with 45 pennies (45 cents) one quarter (25 cents) 2 dimes (20 cents) and 2 nickels (10 cents). 45 + 25 + 20 + 10 = 100
45X1X5X10 = 2250 ways to make 45 cents using pennies nickels and dimes.
Eight ways.
quarter = 25 cents dime = 10 cents, total so far 35 cents 2-nickels = 10 cents, total so far 45 cents 3 pennies = 3 cents, total 48 cents
$1 = 100 cents → 45 cents/$1 = 45 cents/100 cents = 45/100 = 9/20

There is no straightforward answer, you can make it with 50 or 45 coins quite easily if you use 50 one-cent coins or 49 one-cent coins and a 5-cent coin. You could bend the meaning of the question using non-US currencies, or by trading, etc.
fourty-five cents
Oh, dude, you can make 45 cents without using pennies in like... let me count... 5 ways! You can use a quarter and two dimes, or three quarters and a nickel, or even nine nickels. It's like a fun math puzzle, but with coins!

No. Two quarters is overshooting it, and the next highest coin value is a dime. 25+10 isn't enough, so adding another dime will get you to 45 cents, but by then you have already used 3 coins.
