=B887/$B$885=B887/$B$885
What’s the percentage of students from row 2 to row 20 choosing each answer for Question 1?
Click Cell B887 divided by Cell B885 (total number of students) and press Function 4 (F4) on the keyboard. F4 will add $ at the right places in the function to make B885 an absolute number. When you scroll down to repeat the function for answer b, c, and d, the divisor remains the same.
Format Cell C887 into percentage figure.
