18 - 3n
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.
18*10^-2
You can write it as (18, 24) or 18 + 24 iOr use -24 if appropriate.
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

NO!! Irrational Numbers are those where the decimal digits go to infinity AND there is no regular order in the decimal digits. pi = 3.141592.... is the most well known irrational number. as are the 'Square roots' od prime numbers;-# sqrt(2) = 1.414213.... sqrt(3) = 1.73205... sqrt(5) = 2.23606... However, such as numbers as 3.3333..... is NOT irrational, because the decimals are in regular order. Similarly 2.373737.... or 5 .678678678.... Are NOT irrational because the decimals are in a regular order. NB '....''' at the end of a decimal is the mathematical indication of recurring to infinity.
