TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.

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.

Hello,
There is no fraction button, but if you divide two integers (whole numbers) and want to keep the result as a fraction press [MATH][1:|=>Frac] [ENTER]. If the fraction can be reduced to its simplest form that is the result you will have.
27/48 [MATH][1:|=>Frac][ENTER] displays 9/16
Hope it helps.

You do the operation to get a decimal number.
Isolate the integer part (to the left of the decimal point)
Convert the non integer part (decimal part) into a fraction.
Write the result as (integer part) (fraction part)
3/2=1.5
Integer part is 1, decimal part is 0.5
0.5 as a fraction is 1/2
3/2= 1 1/2

If you only cleared RAM, a program that was loaded no longer resides in RAM, but if it was archived, it should still be available.
If you cleared all Including Archives, then it is lost.

the only thing that I can recommend it to stick it in a zip-lock bag full of dry rice for 24hrs. Sometimes there is moisture that you just can't see & rice has a way of attracting liquids from electronic components. Hence, potentially saving your electronic device. If this does work -- if I were you I would suggest always storing your calculator, ritually, in a zip-lock bag so this does not occur again (I do this -- TI-84s are not cheap accessories -- better safe then sorry). Good luck!
