Even nos: 2,4,6

prime nos:2,3,5

ie 1 is the only no. which is not desired

probability of getting one=1/6

hence probability of getting either even or prime no is
= 1-1/6 = 5/6

Is 19/57 in simplest form
No, since 19 and 57 have a factor in common.

Even though you didn't ask, that common factor is 19. Dividing the numerator and denominator by 19 gives 1/3.

How do I reduce a fraction to simplest form on a calculator? I have a Texas Instrument TI30XA calculator. If I wanted to reduce the fraction 15/10 I type in my calculator 15 A/b/c and then 10 A/b/c and...
The key marked [a b/c] has a shifted function marked [d/c]. That is the one you use to convert between fraction display formats.

How do you enter a fraction
A fraction is just a division of two integers. Enter numerator, then press the division key and then the denominator.

If you press ENTER at this time your fraction will be calculated and displayed as a decimal number.
To keep it in fraction form you must press [MATH][1:>Frac]. The result will be a fraction but reduced to its simplest terms (an irreducible fraction).

27 [/] 48 [MATH][1:>Frac][ENTER] gives 9/16

How do u write a fraction on here
Hi,
You can write a fraction by dividing an integer number by another but it will not be displayed as you enter it. It becomes a decimal number.
However, if you want to keep it in fraction form (but reduced to its simplest form) you use the command [|=>Frac] . The arrow is a short, fat one.
To access the command
Press [MATH][1:ToFrac] [ENTER]
Ex: you enter 27/48 [MATH][1:ToFrac][ENTER]
Calculator displays 9/16

So you can keep numbers (in reduced form) by inserting [MATH][1:ToFRac] before pressing the [ENTER] key.

Hope it helps.
Thank you for rating the solution.

On other models of texas instrument calculators they have a button to do a fraction does the ti-84 plus have that?
Hello,
Yes it can do fractions although it does not have a specific key.
If you want to enter a fraction and keep it in fraction form, though reduced to its simplest expression use [MATH][1:->Frac] [ENTER]
Exemple:
27/48 [MATH][1:->Frac][ENTER] displays the reduced form 9/16.
To convert a decimal number into a fraction (with the inherent loss of precision) press [MAT][1:->Frac][ENTER]
Use [MAT][2:->Dec] to convert to decimal, but this is done by default.
Hope it helps.

61/82 as a fraction reduced to lowest fraction
Hello,

This fraction is already reduced to its simplest form because 61 is a prime number: a number that can only be divided by itself and by 1.

Hope it clarifies things.
