Precedence of operators in RPN

Precedence of operators in RPN

While calculating postfix expression in C, if our token is an operator we
have to place it the stack in such a way that it's has the highest
priority.
My question is among the * / % operators which has the highest priority.
Do we need to consider associativity as well ? Since all these operators
have LEFT-TO-RIGHT associativity, will / get higher preference over * ???
