Assuming the result could be expressed as a fraction, use the >FRAC command in the MATH NUM menu. The calculator won't do it if the resulting denominator has more than three digits.

.3684 converts correctly to 921/2500
So it does not have to be a denominator with JUST three digits, but it is not clear to me what the limitations are.
Also .991 converts to 991/1000
But with .999, the calculator does not convert it into a fraction at all.

Unfortunately, you can't. The TI-84 has a limited ability to work with fractions but it won't work with irrational numbers.

### Complex number

Try entering on the same command line your calculation followed by the ToFrac command. That should work. Here is a screen capture from a TI83Plus in complex mode (a+ib).

### My TI 84 won't convert my imaginary numbers to fractions. I typed in 1/(1+i) and it won't convert the answer to fraction form. It keeps saying Error Data Type

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.

The TI-84 doesn't really work with fractions. Type in a fraction as a quotient. For example, to type in one-half, type ( 1 / 2 ).

### How do I on a TI-84 Plus Simplify Fractions

Enter the fraction for example: enter 8/12.
Then click Math (which is located under the Alpha button).
Click the ->Frac button (the first one).
It should come up as Ans->Frac.
Click Enter.
It should now read 2/3 which is 8/12 reduced.
Note: I have a TI-84 Plus Silver Edition, and the TI-84 Plus might not have this function, but that is how I do it on my TI-84 Plus Silver Edition

### Fraction button directions

Yeah, there isn't a fraction button on an 84. You have to enter it manually as 4/9 or if simplifying a decimal, use the Ans>Frac under the MATH menu
