I have this exercise, the result I got is 3/2 instead of the correct answer, which is 2/3 and I don't understand why. See question attached:

4. Wobble's Weebles is the only producer of weebles. It makes weebles at constant marginal cost C(where c > G) and sells them at a price of 131 per weeble in market 1 and at a price of pg per weeble in market 2. The demand curve for weebles in market 1 has a constant price elasticity of demand equal to 2. The demand curve for weebles in market 2 has a constant price elasticity equal to 3J\"2. The ratio of the prot-maximizing price in market 1 to the prot-maximizing price in market 2 is a. 2/3, b. \"3. c. 3\
