The way it works is as follow. If a result is displayed as a fraction you can convert it to its decimal representation. **If you do nothing after the conversion**, you can revert the decimal representation to the fraction.

Convert each mixed number (what you call mixed fraction) to an improper fraction, then multiply the two numerators and multiply the two denominators. Reduce the resulting fraction to its simplest form

Example

(2 1/3)*(1 5/7)=?

Convert 2 1/3 to an improper fraction 2 1/3=2+ 1/3 = 6/3+1/3=7/3

Convert 1 5/7 to an improper fraction 1 5/7=1+ 5/7 =7/7 +5/7=12/7

(2 1/3)*(1 5/7)= (7/3)*(12/7)= (7*12)/(3*7)

The 7's in the numerator and denominator cancel one another leaving

12/3=4

**(2 1/3)*(1 5/7)=4**

Not all products of mixed numbers will give a simple result as this one. More likely they will not.

The F-D key converts a **displayed result** from fraction to decimal and vice-versa.

If in the polynomial expression a numerical coefficient is a fraction just enter it as a fraction, possibly enclosed in parentheses. If it is a decimal number just enter it as a decimal number. Converting it to a fraction is not going to generate any more precision in the result. You lose precision when you go from fraction to decimal, but you do not make a number more precise by converting it from a decimal representation to a fraction.

The MATH menu has two options 1:>Frac, 2:>Dec.

The first entered on the command line after a fraction keeps the result in (reduced) fraction form. On a displayed result, it converts a decimal into a fraction.

The second 2:>DEC converts a fraction into a decimal number.

The latest OS (2.53MP and following) has a better handling for fractions.

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 following examples will demonstrate how to
convert decimals into fractions using the TI-30Xa and TI-30Xa Solar.
Please be aware that TI-30Xa Solar School Edition calculators do not
have this functionality.

**Example**: Convert .25 to 1/4

- Input .25, press [2nd][<--] (says F<>D above it).

**** F<>D means fraction to decimal, decimal to fraction. **

**Example**: Convert 1.38 to 1_19/50

- Input 1.38, press [2nd][<--].

**Example**: Convert 9.75 to 9_3/4

- Input 9.75, press [2nd]{<--].

- Input .25, press [2nd][<--] (says F<>D above it).

- Input 1.38, press [2nd][<--].

- Input 9.75, press [2nd]{<--].

First put the calculator in degree mode.

To convert from fraction to a decimal number first enter your fraction or, mixed number. I'll convert a mixed number to a fraction first since, I don't have a key for the symbol that shows that a number is a fraction on my keyboard. Example: [3][A b/c][1][A b/c][2][A b/cd/e][ENTER]

3/2 should be entered at the home screen. While at the Home screen enter, [2nd][FD][ENTER]

1.5 should now be displayed at the Home screen.

As you can see it is really just using the [A b/c] key to enter in your fraction and, [FD] key to do the converting. The [A_b/cd/e] key isn't necessary because, mixed numbers will convert to decimal numbers just like fractions do. I just don't have the key to show a fraction symbol that the calculator uses. So to show that symbol, I used the / symbol with the fraction number.

To convert a fraction to a decimal or a decimal to fraction you use the [a b/c] key.

While converting a fraction to a decimal number is always possible, converting a decimal to a fraction may, at times, not be possible.

To convert fractions to decimals, and decimals to fractions use the [a b/c] key. If the total number of symbols (num, denom, fraction bar) to display a fraction exceeds 10, the fraction is automatically converted to decimal format.
