What times what equals 18?

Answer 1

There are an infinite number of options. Take any number x, which is not zero. The consider another number = 18/x. Since x is not zero, this number always exists. Their product is

x * 18/x = 18

So, for example, 1 * 18 or 2 times 9 or 1.1 times 18/1.1 or -5 times -18/5 are all equal to 18.

Answer 2

The factor pairs of 18 are:

1 × 18

2 × 9

3 × 6
How about 3 times 6 = 18 as one example
