Hello,
Press [SHIFT][MODE][1:MathIO].
When in MathIO, you can obtain decimal results if you press [SHIFT][=] instead of just [=] to calculate.
Also, you can use the [S<=>D] key to toggle from one display format to the other ( Fraction <-> Decimals) or (Radicals<->Decimals).

Hope it helps.

How i fad the one decimal place the answer of this question 0.7844 correct to 1 decimal place


You haven't made the purpose of the question very clear Miriam so I am only guessing that it is an exercise in rounding or shortening decimal fractions to make them easier to work with which is often convenient when approximations do not matter.

The general rule of rounding is to take the last figure and if it is less than 5 it is erased and if it is 5 or more it is erased but 1 is added to the next or the new last figure and the process is repeated until the fraction is shortened to the required length.

If you take the decimal fraction 0.8745, after the first stage of rounding it would become 0.875 and then after the second stage of rounding it would become 0.88 and then finally rounding to one decimal place the result would be 0.9.

I hope this helps you deal with your fraction. I apologise in advance if I have misunderstood the question.

While using Casio fx-300ES , I am unable to get answers in decimals. For eg. 3/10...should give 0.3, but the answer is again displayed as 3/10. any way to solve this issue?


The calculator has two Input/Output modes: MathIO and LineIO.

LineIO
LineIO is the old way of entering numbers in calculators and results are always displayed as decimal numbers. Some calculators have a fraction feature and would convert a fraction to a decimal number and back.

MathIO
In MathIO you enter expressions as you would by hand or as you see them written in textbooks.
In this mode, results are by default displayed as fraction or fractions/ radicals.
Conversion
To convert the fraction/radical to decimals you just press the [SD] key. If you press again you cycle through all the available display formats.
So you can (if you want) use the MathIO to manipulate expressions and convert only the last result to decimal. By the way, fractions and radicals are generally more accurate than their decimal representations.

SetUP
If however seeing fractions and radicals is too painful, just set the LineIO as your default mode. To do so press [SHIFT][MODE] to open (SETUP), then select [2:LineIO]

Casio-fx300 ES if i enter 2.5+2 it answers as a fraction of 9/2 how do i reset this to calculate correctly


There is a misconception that fraction are less correct than decimal result. Quite the contrary. Calculations with fractions and/or with radicals are exact while decimal calculations are approximate.
Anyway, you want decimals and so decimals you will have.
When a result is displayed in fraction or radical (root form), just press the [SD] key and it will give you the so desired decimal representation.
If somehow you cannot stand the sight of a fraction or a radical, just tell your calculator so.
Press [SHIFT] [MODE] to open (SetUp) screen and press [2:LineIO]

Getting Decimal Answers by Disabling WriteViewelw516.gif on the Sharp EL-W516 Calculator

The Sharp EL-W516's WriteView display uses multiple lines to display mathematics as it is seen on a page. Fractions are shown as fractions, exponents as exponents, integrals as integrals, and so on. This makes entering calculations easier, and reduces the chance of errors.

At the same time, calculation results are displayed as fractions (or with roots or pi) whenever possible. Pressing the CHANGE button repeatedly will change these to decimal answers.
If you prefer to always get decimal results you need to disable the WriteView display mode. Doing this will make the calculator display like the Sharp EL-546W when in NORMAL mode. Answers will be given as decimals, but fractions will no longer look like fractions. In general, you will still need to follow the EL-W516 instructions.
Disabling WriteView

Press 2ndF and MATH to enter SET UP. Now press 2 for EDITOR.

There are now two options: 0: W-VIEW, and 1: LINE

Press 1 for Linear display mode to disable the WriteView display, and to get decimals as your answers.

To return to the WriteView display, go through the steps above but press 0 for W-VIEW.

NOTE: It is not possible to have decimals as the default answer form when in WriteView mode.

I cant find how to make my answer in fraction?! please help.


The default Input/Output mode is MthIO. In this mode result may be fractions or radicals or a mix of both.
To set this mode Press [SHIFT][MODE] to enter the (SETUP) screen, then select [1:MthIO]
ab9d8db.jpg

There is a limitation on how many symbols can be displayed on the screen. If there is not enough space to display the result as a fraction, the calculator will use decimals.

There is a key that can toggle the display from fraction/radicals to decimals. That is the [S<->D] key.

Keep in mind that while you can always convert a fraction/radical result to a decimal one, the reverse may, under ceratin circumstances , not be possible.

How to us a fraction on the ti-83 calculator? I have home work due on this tues. and i dont know how to put a fraction in on this calculator .


Hello,

Ther e is no dedicated key to do that but ther is a command ToFrac noted as ->Frac. To access it use [MATH[1:->Frac].

Two ways of using the command.
1. You want to reduce a fraction to its simplest expression
27/48 [MATH][1:->Frac] [ENTER] gives the reduced fraction 9/16

2 You do not want your results converted to decimal numbers

(27/48) [x] (5/7) [MATH][1:->Frac][ENTER] multiplies the two fractions and gives a fraction as a result. 45/112

3. Your result is in decimal form and you want to cast it into a fraction. The conversion will be exact only for certain numbers. Results kept in fraction forms are more accurate than those represented as decimals.
Hope it answers your question.

When I divide answers are always given in Fractions. Can I change it to come out in decimals?


To change from Fraction display to Decimal display on the Casio fx-300ES (and probably other calculators)

1) Press the "SHIFT" button
2) Press the "MODE/SETUP" button
3) Press the "2" button
This Changes it to LINEIO (Decimal)

Doing all of the above but pressing the "1" button instead of the "2" puts it back into MATHIO mode (Fraction)

Hope this Helps

(SHIFT)(MODE/SETUP)(2) to change to decimal
