Final answer:
The expression 'p divided by 9' is represented as p/9 and is a straightforward algebraic operation where 'p' is a variable. If 'p' is a known number with two significant digits, the result of the division should also be represented with two significant digits.
Step-by-step explanation:
'What is p divided by 9' appears to be a mathematical expression requiring simplification. Without additional context, p is typically considered a variable representing an unknown number in mathematics.
Dividing this unknown number by 9 is represented algebraically as p/9. However, if p is a value known to only two digits as suggested by the provided information, it would simply mean that we express the result to the same level of precision after division, if p indeed is numerical. If p is a variable, we leave the expression as is.
