Oh, dude, totally! You can make 45 cents using 5 coins if you have a quarter (25 cents), a dime (10 cents), and three nickels (5 cents each). That's like basic math, man. So yeah, you can totally make 45 cents with those coins.
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.
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
Eight ways.
$1 = 100 cents → 45 cents/$1 = 45 cents/100 cents = 45/100 = 9/20
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.
There are 4 dimes
45 5 cents
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.
If they are Australian coins, they are all still legal tender. You can take them to a shop and buy something worth 45 cents, or put a deposit on something worth more than 45 cents. You could put it in a money box or give it to a charity.
