You can try pressing "alpha" or "2nd" and then pressing the key you saw the percent sign on.here is a temporary solution in case that doesn't work:to enter a percentage up to write the digits before the tens and ones (if any, and if not, just type a zero), a point, and the last two digits.ex:
- 56%=0.56
- 28%=0.28
- 132%=1.32
- 4243%=42.43
To write down the answer, take all the digits, take off the point, if the percentage is 99% or less, don't write the zero on the right of the period, and add a percent sign.
