What is .705 converted into a decimal


It is already in decimal for. Maybe you mean fraction?
0.705=705/1000=(141*5)/(200*5)
After simplification by 5 you get 141/200

For the Casio fx-9750G II how can I change the sin cos tan into decimal format? I'm not sure i wording this right...


The values of trigonometric functions are real numbers. A few special values are rational such as tan(45 degrees)=1. In general the values are decimal numbers whose decimal representations have an infinite number of digits. Your calculator can only give you an approximation.
So I really do not see what you want.
Some new calculators can give you values with radical (square roots), Calculators with a Computer Algebra System or CAS can do algebra and manipulate roots of higher index.

Hi there,

My name is adieh.have a great day.

I will give a simple example on how to convert your answer into decimal form. Indicated below:

Q: Simplify 1/2-5/13 convert to decimal

Answer:

Step 1: Enter 1/2 by pressing 1>a/b>2.
Step 2: Subtract by pressing - (negative sign or minus sign)
Step 3: Enter 5/13 by pressing 5>a/b>13.
Step 4: Find the difference by pressing = (equals sign)
Step5: Convert to decimal by pressing (change)
You can find( change) on the right side of your calculator beside M+ key

I am suggesting you to visit this website http://files.sharpusa.com/Downloads/ForHome/HomeOffice/Calculators/Manuals/Archive/cal_man_ELW535B_TeachersGuide.pdf
for you to have further knowledge about various functions of your sharp calculator since you are attending a business/algebra class.

Hope it helps.

Thank you for using fixya.

Define algebra:decimal


Decimal is the base-10 notational system for representing real numbers. The expression of a number using the decimal system is called its decimal expansion, examples of which include 1, 13, 2028, 12.1, and 3.14159.

Each of the arabic numerals 0 to 9 is called a decimal digit, and the period placed to the right of the units place in a decimal number is called the decimal point (or, in the case that a comma is instead used for this purpose, the decimal comma).


The decimal is a way of managing numbers that has ten as a starting point, or base. It is sometimes called the base ten or denary numeral system. The word "decimal" is also used instead of the word "period" to point out the dot that is sometimes used separates the positions of the numbers in this system. Almost everyone uses this nowadays and prefers the convenience of it probably because it shows up most often in calculations in nature and has "one" as another starting point for the system. The number one is usually the easiest to work with in calculations.

Need to find the diagonal of a rectangle. Problem is 5' 3 1/2" x 12' 5 1/4". Do I need to convert the fractions to a decimal? I understand to (a)2 x (b)2 = (c)2. The inches with fraction is my problem!...


ra4942 ,

Yes, you would have to convert the fractions into decimal notation, represented as feet.
Example: 5' 3 1/2" is 5.29167'

By the way, the formula (that you know) is "plus", not "times" ....
a^2 plus b^2 = c^2 (the square of the hypotenuse is the SUM of the squares of the two other sides)

How to change a fraction into a decimal


This is a partial solution for I do not have the TI89 titanium with me.
1. The easiest way is to insert the decimal mark (. dot or , comma) at the end of one of the elements of the fraction (numerator or denominator).

Ex: if you enter 1/2 the calculator displays the fraction 1/2, but if you enter 1./2 or 1/2. or 1./2. it displays 0.5

2. You can also configure the EXACT/APPROXIMATE mode option of the calculator ( Press Mode then scroll till you see exact/approximate) then choose AUTO, EXACT, or APPROXIMATE.

In the EXACT option the calculator will perform exact algebra ( Pi remains Pi not 3.14159... ).
In the APPROXIMATE option, calculations are performed numerically (everything is treated as a decimal number.)

In the AUTO option the calculator will try its best to keep the results as exact as possible :
x/6 + 1/2 yields x/6 + 1/2
x/6. + 1/2 becomes .166666..x +1/2
x/6. + 1./2 becomes .16666..x +0.5

My suggestion ( if you allow me) : Leave the calculator set on AUTO, and convert to decimals as needed by putting the decimal mark at the end of an integer.

I hope it helps.

Casio fx-115 es ---- turning decimal answers into radical form


Hello,

Sorry to disappoint you but you cannot do it due to the fact that the representation of irrational (SQRT(2), ..) and transcendental (e, pi, etc.) numbers on a calculator or even a computer is approximative : a number like sqrt(2) has an infinite number of decimal digits while the number of internal digits a calculator uses to store results is limited (10, 12, 15 or even 24).
Once an irrational or a transcendental number has been evaluated numerically it generally ceases to be exact.

If you want to manipulate algebraic expressions, you need a calculator that has a CAS (computer algebra system) operating system and a symbolic algebra option.

Some exemples of calculators with a CAS are The TI nspire CAS, the HP 48 series, HP 49, HP 50, Casio ClassPad3xx, the TI 89titatium, the TI Voyager 200PLT, the TI 92 and Ti 92Plus. The ones with a fullblown keyboard might not be accepted on certain standardized test.

You may also try to get some emulators on the Internet for the HPs or the TI 8xx and play with them on the computer.

Hope that helps.
