Question about Texas Instruments TI-84 Plus Silver Edition Graphic Calculator
There is no key nor command to calculate percentages. But that is easy to correct.
To go from a decimal result to a percentage, move the decimal mark 2 places to the right. If you have no decimal mark as with integers, put a decimal mark at the end of the number pad it with zeros, then move the decimal mark 2 places to the right.
Ex: 0.73 in % gives 73.0%
Ex: 2.33 in % gives 233.00 %
Ex: 5 in % 5=5.00 becomes 500%

Press [ENTER] the result is displayed as a fraction.
