Since 5p is a factor of 20p, it is automatically the GCF.
30p = 20p + 5p + 5p 40p = 20p + 10p + 10p
9 x 5p 7 x 5p, 1 x 10p 5 x 5p, 1 x 20p 5 x 5p, 2 x 10p 3 x 5p, 1 x 10p, 1 x 20p 3 x 5p, 3 x 10p 1 x 5p, 4 x 10p 1 x 5p, 2 x 20p 1 x 5p, 2 x 10p, 1 x 20p
The GCF = 4. 20p - 60pq + 32q = 4(5p - 15pq + 8q).
5px4p=20p 5px5=25p so 20p-25p=-5p
Use 50p, 20p, 20p, 5p and two 2p coins.
20p + 10p + 5p + 1p = 36p
fraction = 1/2 10p/20p = 1/2
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

The simplest way is 2*10p
20p/Â£2 = 20p/200p = 20/200 = 1/10
Two 20p coins and one 5p coin make 45p.
