Question 77

Idea (very simple): A number is called a multiple of \(b\) if we can write it as \(b \times k\), where \(k\) is a whole number.

1. Take any number. Call it \(n\).
2. Choose the whole number \(k=1\).
3. Now write: \(n \times 1\).
4. We know \(n \times 1 = n\).

So we have written \(n\) in the form \(n \times 1\) (with whole number \(k=1\)). Therefore, \(n\) is a multiple of itself. Hence, the statement is true.
