To make 10p using 1p, 2p, and 5p coins, we can use a combination of these coins. We can start by using one 5p coin and five 1p coins, which is one way. Next, we can use two 2p coins and six 1p coins, which is another way. Lastly, we can use ten 1p coins, which is a third way. Therefore, there are three ways to make 10p using 1p, 2p, and 5p coins.
18 5p coins make 90p.
There are 47 ways using 5p, 10p, 20p and 50p.
13 ways. They are:10 x 5p8 x 5p + 1 x 10p6 x 5p + 2 x 10p6 x 5p + 1 x 20p4 x 5p + 3 x 10p4 x 5p + 1 x 10p + 1 x 20p2 x 5p + 4 x 10p2 x 5p + 2 x 10p + 1 x 20p2 x 5p + 2 x 20p5 x 10p3 x 10p + 1 x 20p1 x 10P + 2 x 20p1 x 50pNote that no modern British coins are made of silver, though. Coins of 5p and above are made of copper-nickel.
