you multiply the numbers together, which is 18
You can multiply to numbers with decimals
To get a percentage you have to have two numbers to compare, like 18 out of 100, or 18 out of 37 or basically 18 out of anything. but you can't make 18 into a percentage all by itself.To convert 18 to percent multiply by 100: 18 × 100 = 1,800%
To find this, you first have to split the numbers into their prime factors: 18 = 2x3x3 54 = 2x3x3x3 The next step is to identify any common prime factors. In this case both numbers have a 2 and two 3s as prime factors. Multiply these together gives you: 2x3x3 = 18 Therefore the HCF of 18 and 54 is 18.
If you meant what whole numbers can you use to multiply to 18, there's 9x2, 6x3, and of course 1x18 but you could multiply any number[s] to 18
Multiply 18 by successive counting numbers.
Multiply 11 by 18 and multiply that total by successive counting numbers.

How about: 3 times -6 = -18 as one example

You can multiply the number 18 by different numbers that are relatively prime, for example by different prime numbers.
They are: 1*18 = 18, 2*9 = 18 and 3*6 = 18
3 x6 =18 2 x9 =18 1 x 18 =18
