To make 50p using addition, you can combine different coin values. For example, you could add one 20p coin, one 10p coin, and three 10p coins: 20p + 10p + 10p + 10p = 50p. Alternatively, you could use five 10p coins: 10p + 10p + 10p + 10p + 10p = 50p. There are various combinations of 1p, 2p, 5p, 10p, 20p, and 50p coins to reach the total.
fraction = 1/2 10p/20p = 1/2
