1. 18 times 1 2. 36 divided by 2 3. 19-1 4. 18 plus 18 minus 18 5. 18 in bars srry i could only come up with five good luck anyways
The number 10 can be the product of 2 and 5, 1 and 10. This means that 10 has 4 factors. :]
18 over 4 can be written as 4 and 1/2.
One possible option is 18/10.

You can write it as (18, 24) or 18 + 24 iOr use -24 if appropriate.
18*10^-2
18/5 = 3.6
10 + 8
18/10
18/10 = 1.8
13 and 19 aren't composite. 1,2,5,10 1,13 1,2,3,6,9,18 1,19
The greatest common multiple of 10 and 18 is infinite.However, I suspect you want either:the greatest common factor of 10 and 18 which is the largest number which divides both 10 and 18 and is 2; orthe lowest common multiple of 10 and 18 which is smallest number into which both 10 and 18 divide (ie the smallest number which is a multiple of both 10 and 18) and is 90

yes it is an irrational numberNo because 18 is a rational number
