You buy 2 T-shirts in a sale. You pay the full price of $12 for the first T-shirt, and you get the second T-shirt for half this price. What fraction of the full price do you pay for 2 shirts?

18/24 = 3/4

To find the fraction of the full price you pay for 2 shirts, we need to calculate the total amount paid and then divide it by the full price of 2 shirts.

Let's start by finding the price of the second T-shirt. We are given that it is half the price of the first T-shirt, which was $12. Therefore, the second T-shirt costs $12 / 2 = $6.

Now, let's calculate the total amount paid for both T-shirts. You paid $12 for the first T-shirt and $6 for the second T-shirt, so the total cost is $12 + $6 = $18.

Finally, to find the fraction of the full price you paid for 2 shirts, we divide the total cost by the full price of 2 shirts, which is $12. So, the fraction is $18 / $12 = 3/2.

Therefore, you paid 3/2 of the full price for 2 shirts.
