Yes the answer will be 225/15*15. As / and * has the same precedednce and associativity is from left to right so it will give 225(225/15*15 => 15*15 => 225).

In algebra * has higher precedence than /, but in C they have the same precedence, and are left-associative, meaning the operations are performed left to right.So 225 / 15 * 15 gives (225/15)*15 or 22...
