Since we have no more information, I believe, unless I am mistaken that the least quotient that generates no remainder is 1
1 liter is equal to 1000 milliliters, so we can multiply 200 liters by 1000 to get 200000 milliliters, which should be your answer. In general, the "milli-" prefix denotes a factor of one thousand times smaller, so 1 meter is equal to 1000 millimeters, 1 second is equal to 1000 milliseconds, and so on.
Let x = hours worked as a clerk ($12 per hour).Let y = hours worked as a cashier ($8.25 per hour).She worked 55 hours, thereforex + y = 55 (1)She earned $585, therefore12x + 8.25y = 585 (2)From (1), obtainy = 55 - x (3)Substitute (3) into (2).12x + 8.25(55 - x) = 58512x + 453.75 - 8.25x = 5853.75x = 131.25x = 35y = 55 - x = 55 - 35 = 20
Answer: c) Office clerk: 35 hours; cashier: 20 hours.
