### Mark has zero marbles. He wants to put them in 6 boxes. How many marbles are there in each box?

0

Step by Step Explanation:
1. According to the question, Mark has zero marbles and wants to put them in 6 boxes.
2. Since there are zero marbles, all the boxes remain empty.
3. Let us prove the above conclusion mathematically.
As we know that any number multiplied by 0 gives the result as 0.
i.e., 6 × 0 = 0,
which can be written as: 0 ÷ 6 = 0
So, when '0' is divided by a non-zero number, the quotient comes out to be 0.
4. Therefore, there are zero marbles in each box.
