"Grandmother is happily eating soup with potatoes."
Translation:Бабушка с удовольствием ест суп с картошкой.
I am confused about when you need to specify the "с." I wrote
Бабушка ест суп картофелем с удовольствием"
which I had hoped implied the "c" for "картофелем." Also, I thought the most important part was that she was eating it happily, so I put that at the end.
Am I incorrect here?
