Question #3 asks: What is the ratio of 3a =4B? The correct answer is, B, statement 2 alone is sufficient. The answer explained states that this problem can be rewritten as, a/b = 3/x, the ratio of a to b is 4 to 3. How do they come up with that equation? I know that it's simple algebra, but when I use the rules of algebra I get, a =4b/3 with x being the unknown symbol for ratio. How do incorporate the x into this and get the answer they state? The problem is on page 101 of the assorted topics chapter. Can anyone help me?
Thank you, wardstein

can you please post the question statement and statement B.

From what has been stated in your earlier post, a/b = 4/3. But the question is asking what is the ratio of 3a = 4b. That statement does not make sense. It should probably be what the ratio of 3a : 4b and some information about a and b should be given in statement B.
