The ratio of the number of Singapore stamps to the number of malaysia stamps samuel has is 6:11. Samuel has 12 singapore stamps. How many more malaysia stamps than singapore stamps does he have?
Since the ratio of singapore stamps to malaysia stamps is 6:11, this means that for every 6 singapore stamps, there are 11 malaysia stamps.
Since Samuel has 12 singapore stamps, this means he has 12*(11/6) = <<12*(11/6)=22>>22 malaysia stamps.
Therefore, Samuel has 22-12 = <<22-12=10>>10 more malaysia stamps than singapore stamps. Answer: \boxed{10}.
