Lizzy: Jon makes 3/4's the salary that Karen makes. John makes $3000 per month. How long will it take him to make the same amount of money that Karen does in 3 months?.
Me: Hmmm, let me think. I think this is the detailed solution:

Karen makes $3000 / (3 / 4) = $4000 per month. In three months, Karen would make a total of $4000 * 3 = $12000. To make the same amount of money John would need to work $12000 / $3000 = 4 months. Final answer: 4.
