To convert marks taken for 100 to 80, you would first calculate the percentage decrease in marks. This can be done by subtracting 80 from 100 to get 20, then dividing 20 by 100 to get 0.20 or 20%. Next, you would multiply each mark by 0.80 (1 minus the percentage decrease) to obtain the equivalent mark out of 80. For example, a mark of 90 out of 100 would be converted to 72 out of 80 (90 x 0.80 = 72).
