Question

question: 3
you are splitting up all of your apples equally between 3 people. which statement below will calculate how many apples will be left over?

• let leftover = numapples / 3;
• let leftover = 3 / numapples;
• let leftover = numapples % 3;
• let leftover = 3 % numapples;

Explanation:

Step1: Recall the concept of remainder

To find the number of apples left over when dividing by 3, we need the remainder of the division of the number of apples (\(numApples\)) by 3. The modulus operator (\(\%\)) in programming gives the remainder of a division operation.

Step2: Analyze each option

• Option 1: \(let\ leftover = numApples / 3;\) This does division (gives quotient), not remainder.
• Option 2: \(let\ leftover = 3 / numApples;\) This divides 3 by the number of apples, not relevant for remainder of dividing apples by 3.
• Option 3: \(let\ leftover = numApples \% 3;\) This uses modulus to get the remainder when \(numApples\) is divided by 3, which is the leftover apples.
• Option 4: \(let\ leftover = 3 \% numApples;\) This gives the remainder when 3 is divided by \(numApples\), not what we need.

Answer:

The correct option is: let leftover = numApples % 3; (the third option among the given choices)
