Ethan is thinking of a negative number that is lower than -4 and higher than
s2008m [1.1K]

When the number is odd and a multiple of 3, the number that Ethan is thinking of is -9.

<h3>How to illustrate the number?</h3>

In mathematics, a multiple is the product of any quantity and an integer. It should be noted that, for the quantities a and b, it can be said that b is a multiple of a if b = na for some integer n, which is called the multiplier. If a is not zero, this is equivalent to saying that b/a is an integer.

In this case, Ethan is thinking of a negative number that is lower than -4 and higher than -10 and his number is odd and a multiple of 3. The number is -9 since 9 is a multiple of 3.
