Question

3 brothers share some cash. The ratio of Mark's and David's share is 1:2. The ratio of David's and Paul's share is 1:2. What is the ratio of Mark's share to Paul's share?

Answer 1

Someone may correct me if I am wrong, but I think as
M:D = 1:2, and
D:P = 1:2,
You can times the second ratio by 2, to get
D:P = 2:4
Then equate
M:D:P = 1:2:4

Ie, M:P = 1:4

Answer 2
