Assuming you want the amount of milk in 7 days, we can set up a multiplication problem. Given Minka pours 1/4 cup of milk in her oatmeal each day, we can multiply that by 7 days to find that:
1/4 = 0.25
0.25 • 7 = 1.75, or 1 3/4
By the end of 7 days, Minka pours 1 3/4 cups of milk into her oatmeal collectively.
