The doctor told Cheryl to drink 4 liters of water a day. After 7 days, how many milliliters of water did Cheryl drink? If she has to drink a minimum of 80,000 milliliters before she can participate in sports, how many days should it take?

4 liters of water a day??!! OK!.

 

4 x 7 = 28 liters of water that Cheryl has to drink.

1 liter = 1,000 ml.

28 x 1,000 =28,000 ml. of water that Cheryl has to drink in 7 days!.

 

4 x 1,000 =4,000 ml. of water per day.

80,000 /4,000 = 20 days - time it will Cheryl to drink 80,000 ml. of water.
