The institute of medicine determined that a man should drink 3 liters of fluids and a woman should drink 2.2 liters. mr. morrison drank 880 ml of water at breakfast and mrs. morrison drank 700 ml. how much more will they both need to drink combined to meet the recommended amounts for the day?

According to the question,

Man needs to drink = 3 liters of water a day = 3000 ml

Women needs to drink = 2.2 liters of water a day = 2200 ml

Mr. Morrison drank = 880 ml
Mrs. Morrison drank = 700 ml

Total water needed to be drink by both men and women = 3000+2200 = 5200 ml

Total water drank by Mr. and Mrs. Morrison = 880+700 = 1580 ml

Water they both need to drink combined to meet the recommended amounts for the day = 5200 - 1580 = 3620ml
= 3.62 liters

Hope this helps!
