Reasoning and answer: The car consumed 47 liters - 14 liters = 33 liters of gasoline for 275 km. Let x be the fuel consumption per 100 km. We can write the proportion: 33 / 275 = x / 100. The cross product gives: 275 x = 33 * 100. So the car consumes x = 3300 / 275 = 12 liters per 100 km.
The answer: 12

Reasoning and answer: Anne and her brother use 1 gram + 1 gram = 2 grams. Anne's dad uses 3 grams and Anne's mom uses 2 grams so together they use 2 grams + 3 grams + 2 grams = 7 grams / wash. Each day, the family uses 7 grams / wash * 3 washes / day = 21 grams. Using that amount daily, the toothpaste will last 105 grams / 21 grams / day = 5 days.
The answer: 5
