SOURCE: how to change or put math mode without fractions

I am not sure what you want because the mathIO mode IS THE ONE THAT DISPLAYS results as fractions.

You have two display modes: MthIO (with fractions, radicals) and LineIO (with decimals). Which one do you want?

To set MthIO press [Shift][MODE][1:MthIO]

To set LineIO, press [SHIFT][MODE][2:LineIO]

Concerning the scientific display mode.

Decimal numbers can be displayed in various formats, Fixed,Scientific, and Normal. If you do not want scientific display of results, just set the mode to Fix(ed) and specify the number of decimal digits. However if a number to be displayed (a result) is too small or too large IT WILL BE DISPLAYED in scientific format regardless of the mode you selected.

SOURCE: how do i convert 1.695652174

Answer is 39 over 23......or 1 and 16/23. Check your settings on the calculator. People are running into this problem with decimals and there is an easy fix.

Let's say you have a repeating decimal such as .16666.....If you type in .166 or .1666 or .16666 and check as fraction it will NOT work. Reason why is you haven't typed enough of the "repeating" numbers for the calculator to understand that it is in fact "repeating." If you have a single number ie. 1-9 you must type in a minimum of 11 of that number. Then it WILL work as fraction.

Let's say you have a 2-digit number such as 13. Then you need to type in at least 6 of that number. Say you want to convert 1.2181818 where 18 keeps "repeating." Well I only typed it in 3 times. It won't work to convert. But type in that repeating number 6 times and it will.

Again calculator need to know that it is in fact repeating. Only typing it in a couple times could still change the outcome so it will basically fail to show the fraction until it knows for sure.

SOURCE: when i type in a decimal and then hit math and try

Yes, there is a feature or, setting in the mode that will stop you from converting fractions. Go to the mode screen by pressing the [MODE] key. [Down arrow] 9 times and, highlight and select the n/d by pressing the [ENTER] key. Next, [Down arrow] 1 time and, highlight and select Frac by pressing [ENTER] key. Just escape or, quit out of the mode screen and, the calculator should now be set up to convert your fractions. Just remember to go back and, change the last setting you made when you go back to dealing with decimal numbers.

One way to solve the problem is to convert all the fractions so that they have the same common denominator, then just add them up.

**12 1/6** = 73 / 6 = 292 / 24

**2 3/8** = 19 / 8 = 57 / 24

**7 2/3** = 23 / 3 = 184 / 24

**19 3/4** = 79 / 4 = 474 / 24

Therefore:

(292 / 24) - (57 / 24) - (184 / 24) + (474 / 24) = 525 / 24 = 21 21/24 = 21 7/8

Therefore:

12 1/6 - 2 3/8 -7 2/3 + 19 3/4 = 21 7/8

Good luck, I hope that helps.

(292 / 24) - (57 / 24) - (184 / 24) + (474 / 24) = 525 / 24 = 21 21/24 = 21 7/8

Therefore:

12 1/6 - 2 3/8 -7 2/3 + 19 3/4 = 21 7/8

There isn't one. You can convert some values to fractional form by using the >Frac command on the Math menu available by pressing the MATH key. You can enter a fraction as a quotient, but the calculator deals with the number internally by converting it to decimal form.

For example, to see one-half plus one-third, press

( 1 / 2 ) + ( 1 / 3 ) MATH 1 ENTER

For example, to see one-half plus one-third, press

( 1 / 2 ) + ( 1 / 3 ) MATH 1 ENTER

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.)

A fraction is in fact a ratio of two number: a division of a numerator by a denominator. The key used for the division operation is the one above the multiplication sign and below the caret [^], and in thee rightmost column of keys.

Beware that this calculator converts any ratio of two numbers into a decimal value. To keep a fraction in a fraction form you must use the [|=>Frac] or [ToFrac] command. To convert a decimal result to a fraction, use the [|=>Dec] command.

These commands are accessible through the CATALOG or more easily by pressing [MATH] (under the ALPHA key) and selecting [1:|=>Frac], or [2:|=>Dec]

Ex: to keep 27/48 in fraction form you enter

27 [/] 48 [MATH][1:|=>Frac] [ENTER]. Result is 9/16

You will notice that the resulting fraction is reduced to its simplest form.

To convert the above result from fraction to decimal press [MATH][2:|=>Dec]

A fraction can always be approximated by a decimal value but the converse is not always possible.

Hello,

Press [MATH][1:ToFrac] to convert an aswer to fraction.

If you enter 18.52[ToFrac] [ENTER gives 463/25

[MATH][2:ToDEC] converts a fraction to a decimal number.

Hope it helps.

Hello,

There is no fraction button. Any division of two integers you do is represented as a decimal number. If you want your fraction to remain a fraction you enter it as follows

**7[ / ] 19 [ MATH][1:ToFrac] [=] displays 7/19**

If you want to convert a decimal number into a proper fraction press**[MATH][1:ToFrac] .**

Exemple 7/19 [ENTER] gives .36842105. If without doing anything else, you press [MATH][1:ToFrac] you recover 7/19.

There are limitations related to the number of decimal digits in the floating point number.

.3684 [MATH][1:ToFrac][=] gives 921/2500 but

.36842 [MATH][1:ToFrac][=] gives .36842 : it is not converted to fraction.

Hope it helps

Hello,

Once you enter a fraction the calculator calculates it and displays a decimal result.So basically you cannot do fraction manipulations. However you can convert a decimal result into a fraction. To do the conversion, you enter the decimal number then you Press [MATH] and [1]. (** -->Frac)** The number will be converted.

Similarly you can enter a fraction to a decimal number**(-->Dec)**

[MATH] [2:] [ENTER]. But I see no point in doing that, because any fraction entered is displayed as a decimal number.

Hope it helps
