Consider the question. Emily loves to have pets and for that reason, she has 4 dogs in her home. Each one eats 250 grams of food per day. She has to go on vacation for 14 days. How many kilograms of food should she buy for her 4 dogs so they don't starve while she is out?
 What is the step-by-step reasoning process to arrive at the answer: 14?
Each dog would eat 250 grams so 4 will would eat 4 x 250 grams = 1000 grams of food per day. 1.000 grams is equal a 1 kilogram. Emily is going on vacation for 14 days and with the 4 dogs together eating 1 kilogram of food per day, 14 days x 1 kg of food / day = 14 kg of food would be enough for two weeks.
