Answer:
459.2 liters.
Step-by-step explanation:
Let us convert our given amount of rolled oats and water in deciliters.
1 liter = 10 deciliters
19 liters = 19*10 deciliters = 190 deciliters.
![\text{Total amount of rolled oats consumed per day}=(190+2)\text{ deciliters}](https://tex.z-dn.net/?f=%5Ctext%7BTotal%20amount%20of%20rolled%20oats%20consumed%20per%20day%7D%3D%28190%2B2%29%5Ctext%7B%20deciliters%7D)
![\text{Total amount of rolled oats consumed per day}=192\text{ deciliters}](https://tex.z-dn.net/?f=%5Ctext%7BTotal%20amount%20of%20rolled%20oats%20consumed%20per%20day%7D%3D192%5Ctext%7B%20deciliters%7D)
46 liters=46*10=460 deciliters
Now let us find weekly consumption of oats and water by multiplying daily consumption of both items by 7.
Let us convert weekly consumption of water and oats into liters.
![\text{Total weekly consumption of oats and water}=\frac{4592\text{ deciliters}}{10}\cdot\frac{\text{ liters}}{\text{ deciliters}}}](https://tex.z-dn.net/?f=%5Ctext%7BTotal%20weekly%20consumption%20of%20oats%20and%20water%7D%3D%5Cfrac%7B4592%5Ctext%7B%20deciliters%7D%7D%7B10%7D%5Ccdot%5Cfrac%7B%5Ctext%7B%20liters%7D%7D%7B%5Ctext%7B%20deciliters%7D%7D%7D)
![\text{Total weekly consumption of oats and water}=\frac{4592}{10}\text{ liters}](https://tex.z-dn.net/?f=%5Ctext%7BTotal%20weekly%20consumption%20of%20oats%20and%20water%7D%3D%5Cfrac%7B4592%7D%7B10%7D%5Ctext%7B%20liters%7D)
![\text{Total weekly consumption of oats and water}=459.2\text{ liters}](https://tex.z-dn.net/?f=%5Ctext%7BTotal%20weekly%20consumption%20of%20oats%20and%20water%7D%3D459.2%5Ctext%7B%20liters%7D)
Therefore, total weekly combined consumption of oats and water is 459.2 liters.
