Let's solve this step by step. We have a baby elephant that eats 122 kilograms of food per day, and an adult elephant that eats 3 times as much as the baby elephant. We need to find the total amount of food the zookeeper must prepare daily for both elephants.
First, let's calculate how much food the adult elephant needs. Since the adult elephant eats 3 times as much as the baby elephant, we multiply 122 kilograms by 3. This gives us 366 kilograms per day for the adult elephant.
Now for step 2, we need to calculate the total amount of food required for both elephants. We add the baby elephant's daily consumption of 122 kilograms to the adult elephant's daily consumption of 366 kilograms. This gives us a total of 488 kilograms of food needed per day.
Let's summarize our complete solution. In step 1, we calculated that the adult elephant needs 366 kilograms of food per day by multiplying 122 by 3. In step 2, we added the baby elephant's 122 kilograms to the adult elephant's 366 kilograms to get our final answer. Therefore, the zookeeper needs to prepare 488 kilograms of food every day for both elephants.
This problem demonstrates an important problem-solving strategy. First, we identify what we know: the baby elephant eats 122 kilograms per day, and the adult eats 3 times as much. Next, we calculate the missing values using multiplication. Finally, we add both amounts to find the total. This systematic approach can be applied to many similar word problems involving multiplication and addition.
