Question about Texas Instruments TI-83 Plus Calculator
Unlike other, less sophisticated calculators, the TI83Plus /TI84Plus /TI84Plus Silver Edition do not have a simple key or a command for improper fractions. However there is a command -->Frac accessible through [MATH] key [1:-->Frac] that expresses a result in a proper fraction format.
Here is how you would enter you calculation
3+ 1/2 +4+1/8 [MATH][1:-->Frac][ENTER] result is 61/8
You can also ease a bit on the typing by mentally adding 3 and 4
7+ 1/2 +1/8 [MATH][1:--Frac][ENTER]
You should know about the other command that converts a fraction in decimal format. [MATH][2:-->Dec][ENTER]
If you enter this command just after the one handled above, your screen shows [Ans][-->Dec] on one line and the result 7.625 on the next. If you do not enter a number the calculator uses the last CALCULATED result, which is stored in the system variable [Ans]
Hope it helps
