Jennifer made 5 l of punch for her party. her brother made another 750 ml. if they combine the two batches, how many 180 ml servings would they have? would there be any punch left over? if so, how much

Let's convert 5 L to mL. There are a 1000 mL in 1 L. So, clearly, 5 L = 5000 mL. Now, let's add to see how much punch they made in total:


They made 5750 mL in total (her and her brother). Now, to see how many 180 mL servings that is, we can simply divide:


So, they would have 31 servings of 180 mL of punch. There would also be 0.944 of 180 mL left over which is 169.92 mL. All in all, your answer is:
They would have 31 servings of 180 mL, and 169.92 mL left over.
