The [U n/d] key allows users to input mixed fractions using the TI-30XS/B or TI-34 MultiView scientific calculator. For example, to input 2 3?4, follow the instructions below:
• Input 2 and press [2nd] [U n/d].
• Input 3 and press [down].
• Input 4 and press [right] [enter].

Shows an L


Some fraction symbols do look like mirrored L or r. It shows if you press the fraction key, or if the result is displayed as a fraction. On older calculators the fraction key is marked [a b/c].

How to convert a fraction into a decimal


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.

I have to learn how to operate a texas instrument TI-83 to do math (fraction)


This calculator, although very sophisticated, is rather unfit for heavy fraction calculations. There is no dedicated fraction key, but you can use the [MATH] menu to access a ToFraction command: symbolized by a fat arrow and Frac.
I am enclosing a few screen captures to help you figure out how to use your calculator to manipulate fractions. To get the first screen you press the [MATH] key (below the [ALPHA] key. The ToFraction command is the first one in the list. The second item allows you to convert a fraction to a decimal number.

In the following screen I show you how to enter a fraction (division key) and keep it in fraction form, albeit reduced. Fractions are reduced to their simplest terms

In the last screen, I show you how to convert a fraction to a decimal number by making use of the ToDecimal command (last command line on the left, result is one line down and to the right.)

Casio fx-300ES Default answer readout?


Hello,

Generally, MathIO gives results in fractions or radicals. But sometimes it does not. I tried multiplying or dividing fractions or radicals by integer numbers, and once in while I got a decimal result and was unable to cast it into a fraction or a radical. I was not able to find the pattern.
In lineIO you only get decimal results.
What can one tell you that you cannot determine for yourself? If you appreciate the functionalities of the MathIO, it seems like an insignificant price to pay to press ONE button to switch between displays. It needs to be done ONLY once, for the last result one wants to record.
Your calculator, Your rules. But sometimes one cannot eat the cake and have it too.

Answers show in fraction form. how do i switch it


I know that you can press the S↔D just above the DEL key. By pressing this key the answer will toggle between fraction and decimal display. As far as locking the calculator into a mode that will default to decimal results, well... that's why I'm here looking.

I think the F-D function only works one direction from fraction to decimal. Decimal to fraction is a non trivial calculation that can have multiple answers so doesn't lend itself to a calculator feature.

TI-30xa Calculator Reciprocal Key


It does. For instance, to get the reciprocal of 4, enter the following sequence: 4 [1/x] (this last key to be found third row down, second black key in). The decimal 0.25 will appear as the result. Convert this, if you want, to the fraction 1/4 by pressing the yellow function key [2nd], then {F<>D] located bottom, far left. Hope that's what you wanted!
