b is two thirds of c. 5a = 4c Work out the ratio a : b : c Give your answer in its simplest form where a, b and c are integers
a : c = 4 : 5 and b : c = 2 : 3 so getting a common value of 15 for B gives a : c = 12 : 15 and b : c = 10 : 15 we can now compare these ratios and get 12 : 10 : 15 this is not divisible by any common factor so it is in its simplest form
