Changing An ambiguous to unambiguous grammar

I want to transform an ambiguous grammar to unambiguous one. You can find the first one in the file i have uploaded.

In order to do that you have 5 rules

1) * and / have the same priority

2)+ and - have the same priority

3) *and / have bigger priority that + and -

4)all ops have left associativity

5)the reduction of the first 4 rules is prefered unless it doesnt violate the associativity and priority of ops
