Hurley drank between 4 and 5 liters of water for 8 different days and drank between 1 or 2 liters of water on 4 different days. To find the answer we have to use the following equation.
# of days Hurley drank (4-5 L) - # of days Hurley drank (1-2 L) = # of more days
8 - 4 = 4
In a group of 100 people, 2/5 prefer chicken soup, 4/10 prefer to eat hornado, and the rest prefer frying. What part of the group prefers frying ? How many people prefer each type of food ? (thank u google translate)...I guess
2/5 of 100 prefer chicken soup.....so thats 2/5 * 100 = 200/5 = 40 prefer chicken soup.
4/10 out of 100 prefer hornado (I dont even know what that is)...
4/10 * 100 = 400/10 = 40 prefer hornado.
and the rest prefer frying....100 - (40 + 40) = 100 - 80 = 20 (or 1/5) prefer frying
