What is the dimensional formula of the term `(a)/(b)` in the equation `P=((a+x)/(b))`, where P is the pressure and x is the distance?

The dimensional formula of (a/b) in the equation p=(a-ct)/(bx) ,where P=pressure,x=displacement & time

Write the dimensions of a//b in the relation P = ( a - t^(2))/( bx) , where P is the pressure , x is the distance , and t is the time .

Write the dimensions of a//b in the relation P = ( a - t^(2))/( bx) , where P is the pressure , x is the distance , and t is the time .
