The TI-84 graphing calculator, developed by Texas Instruments (TI), is a multifunction device that allows users to solve equations in a matter of minutes. Whether you are in a classroom environment or not, having a percentage in decimal form can seem confusing. With a simple calculation and a few keystrokes on the TI-84, you can turn the decimal into a whole-numbered percentage.
Enter your function into the TI-84 calculator and press the "Enter" button located in the bottom-right corner of the keypad. An answer will appear in decimal form. For example, if you entered 4/5 into the calculator, your answer would be 0.80.
Press the "Multiplication" button on the right side of the keypad and enter "100."
Push the "Enter" button again to obtain a percentage. For example, if your decimal was 0.80, the percentage would be 80% (0.80 x 100 = 80).
