A recipe that serves 6 people needs to be doubled to serve a dinner party of 12. The original recipe calls for 3 3/4quarts of milk. How many quarts of milk should you use to double the recipe?
Please break it down for me, I've tried so many different equations only for the answer to be wrong!

I figured it out, 6/12 simplifies to 1/2 and 3 3/4 = 15/4. Do (2/1)(15/4), your answer will be 30/4. The mixed number will be 7 2/4. Simplify it to 7 1/2.
3 3/4 = 3 + 3 / 4 = 12 / 4 + 3 / 4 = 15 / 4
2 ∙ 3 3 /4 = 2 ∙ 15 / 4 = 2 ∙ 15 / 2 ∙ 2 = 15 / 2
= ( 14 + 1 ) / 2 = 14 / 2 + 1 / 2 = 7 + 1 / 2 = 7 1/2
2 ∙ 3 3 /4 = 2 ∙ 15 / 4 = 2 ∙ 15 / 2 ∙ 2 = 15 / 2
= ( 14 + 1 ) / 2 = 14 / 2 + 1 / 2 = 7 + 1 / 2 = 7 1/2
Your answer is correct.
