<PRE><B>Question 810293</B>
A jar contains marbles in the ratio of 11 red to 5 black. 
If there 230 black marbles, how many red marbles are there?
-----
11:5 is the same as 11x:5x where 5x is the number of black marbles.
-----
Solve:: 5x = 230
x = 46
------
Then # of red = 11x = 11*46 = 506
