Question

A small banana contains 323 mg of the nutrient potassium. You would need to eat _____ small bananas in one day to obtain the recommended daily intake of 3.5 g of potassium.

Answer 1

So 1g is 1000mg. 
You would need to eat 3500mg worth of a bannana, so divide 323 with 3500..
3500 / 323 which is 10.80.. So you'd need to eat about 11 small bannanas.
