Reported effective tax rate

CFAI text Vol 3, P.502

At the bottom of this page, it is stated : Reported effective tax rate = Income tax expense + Pretax income (accounting profit)

I don’t understand what this means ! The left side of the equation is rate (%) whereas the right side is amount, how the left side = right side ?

Anyone can help me ?

Anyone can clarify ?

Very sorry ! Please ignore my above messages. I mistook the sign in the equation.
