Answer:
16.8 cups
Step-by-step explanation:
We are given that there are 4.2 cups in in 1 liter of a liquid and we are to find out the number of cups that there will be in 4 liters.
To find this out, we will use the ratio method.
We know that:
1 L = 4.2 cups
So we can write it as:
![(1L)/(4 L) =(4.2 cups)/(x)](https://img.qammunity.org/2020/formulas/chemistry/middle-school/nq2ukgtuixr9enpzbrsfl8733vkq01abld.png)
![x = 4 .2 * 4](https://img.qammunity.org/2020/formulas/chemistry/middle-school/ly7eno5aw5ymgawu0sy0vwumxksq510c5q.png)
![x = 1 6 . 8](https://img.qammunity.org/2020/formulas/chemistry/middle-school/932posji3x9mp58ircsbvh5bl5nwqu4pr7.png)
Therefore, there are 16.8 cups in 4 liters.
