Data Editor and List Conversions

v

v lets you enter data in up to 3 lists. Each list can contain up to 42 items. Press % # to go to the top of a list, and % $ to go to the bottom of a list.

List conversions accept f³´d, ´%, ´Simp, and n/d³´Un/d.

Numeric notation, decimal notation, and angle modes affect the display of an element (except fractional elements).

Example

L1

v 1 P 4 $ 2 P 4 $ 3 P 4 $ 4 P 4 <

Conversion

" v "

 

<

 

v < % j

 

<

Notice L2 is calculated per the conversion you entered, and L2(1)= in the author line is highlighted to indicate the list is the result of a conversion.

³ Problem

Find the decimal representation of , , and . From this pattern, can you predict the decimal representation for ? Check your answer using the lists on the calculator.

v v 4

v " 5

1 P 9 $ 2 P 9 $ 3 P 9 <

" v " 1

v 1 % j

<

Input the rest of the fractions to test your pattern. Notice L2 updates as you enter in L1.

The pattern appears to show that the decimal representation is a repetition of the number in the numerator for ninths. Entering , , and finally validates that statement. Notice the last digit in the list is rounded, so 0.777777… is shown rounded to 0.77778.
