To determine how many 50p coins are in £10.00, you first need to convert £10.00 into pence. Since there are 100 pence in a pound, £10.00 is equal to 1000 pence. Next, you divide 1000 pence by 50 pence to find out how many 50p coins are in £10.00. The answer is 20, so there are 20 50p coins in £10.00.
10 because 50p x 10 = 500 p = £5
To find the number of ways to make 50p using the given coins, we can use a technique called dynamic programming. We can create an array of size 51 to store the number of ways to make each value from 0 to 50p. We initialize the first element as 1 (since there is one way to make 0p), and then iterate through each coin denomination, updating the array based on the current coin value. Finally, the value at index 50 of the array will give us the total number of ways to make 50p using the given coins.
Different countries have different coinage. You have not specified a country. In the UK, for example, you could do 50p + 20p + 20p + 20p + 10p + 5p = 1.25p
£1 coin + 50p coin + 2x20p coins + 10p coin = £2
