Okay. Next, let's lay out a plan of what we have to do.
1. Divide 220 by 7 (because we need to know how many sets of 7 are in 220 in order to solve the problem)
2. Multiply the answer of 220/7 by 12 in order to find the number of minutes it will take.
Let's start!!!
Step 1: Divide 220 by 7
I got 31.42857142857143
Next step! Multiply the answer by 12
31.42857142857143 * 12
I got 377.1428571428572
So, your final answer will be 377.1428571428572 minutes, or you could round it to the nearest tenth 377.1 minutes, or just round it to the nearest whole 377.
You can also put it in hours. To do this, just divide by sixty to get 6.285714285714286.
Hope this helped! Comment if you have any questions!!! :)
no tables were provided but if a cup is 3/4 water and 1/4 citric acid and the other is 1/4 water and 3/4 citric acid then it's the second one. Basically it the one with the most citric acid.
