Explanation

The common element between both proportions is b, so that’s what you’ll want to start with. However, the numerical value of b does not match from proportion to proportion, so you’ll essentially want to find a common multiple for both values of b. Both 4 and 6 are factors of 12, so use 12 as your common multiple. For the first proportion, you’ll need to double it in order to make b = 12. When you do so, a = 22. For the second proportion, you’ll need to triple it to make b = 12. Therefore, c = 9. Now that the two proportions have the same value for b, you know that a:c equals 22:9, which can be written as a fraction.

Hence answer is $$\frac{22}{9}$$ correct!

$$\frac{22}{9}$$

Notice that (a/b)(b/c) = a/c

Given: a/b = 11/6 and b/c = 4/3

So, (a/b)(b/c) = (11/6)(4/3)
= 44/18
= a/c

So, the ratio a to c = 44 to 18

On the GRE, you would be asked to express the ratio as a FRACTION.
So, we could just enter 44/18

IMPORTANT: When entering fractions on numeric entry questions, we aren't required to simplify the fraction.

So, 44/18, 22/9 and even 440/180 are all considered correct responses.

Cheers,
Brent
