Ratio calculations

Hello sir, i hope you are doing well!
My question is should we show the calculations for ratios in Section B questions for AA.

For example if the gross profit margin is 33%; then just typing 33% in Section B is enough? Or do i have to show the entire calculation (33/100)*100 =33%.

I end up taking more time to show the entire calculation and given the time limit; it is very important to know its need in a constructed response question.

Thank you
