Ti 84 plus silver edition decimal won't convert to fraction

SOURCE: I need to know how

Press the MATH key to display the Math menu.

>Frac converts a decimal value to a fraction.
>Dec converts a fraction to a decimal value.

SOURCE: With the TI-84 Silver calc: what I really meant

Upgrade the OS of the calculator to the 2.53 MP (Math Print) version. As you can see on the following screen capture of the MODE setting, you can choose to use the CLASSIC option (the old way) or the MathPrint version.
You should notice that the Answers AUTO DEC or FRAC options allow you to configure the calculator to work in DECimal, FRACtions or AUTO (the calculator chooses whats is appropriate).
The n/d is for improper fractions and Un/d for mixed fractions.

Enjoy your new found freedom.

The >FRAC command only works for real numbers. For complex numbers you have to convert the two components separately.

Unfortunately, there is not a simple solution to this, however there is a solution. It is easy to get it displayed as a fraction using the >Frac from the MATH button. It is also easy to find that 24 goes into 55 two times. Now, there is a function that is on the calculator Remainder. This can be found either in the catalog or by going to MATH arrow to NUM and Remainder should be listed. So, you could type Remainder(55,24) and it will return 7. Seven is the numerator and 24 will still be the denominator. So, it is not an extremely fast way to find the mixed number, but it works.
An alternative to using the remainder function would be to just type 55-24(2), which would also return 7. Either method works, just a matter of preference.
Best Wishes!

The TI-84 works with real fractions. It will not convert complex numbers to fractions.

You can convert the real and imaginary components to fractions separately. For your example, 1/(1+i) is .5-.5i. Converting .5 and -.5 to fractions, you get 1/2 + (1/2)i.
