If 4S = 5R, this means that each unit of S is bigger than R because you only need 4 of S to be equal to 5 of R hence the ratio is 5:4 instead.
4S = 5R
1S = 5/4 R (this shows that S is more than R as 5/4 is more than 1)
4S = 5R
1S = 5/4 R (this shows that S is more than R as 5/4 is more than 1)
O, understand now. Thank you.
