Question about Texas Instruments TI-30XA Calculator

Does the TI-30x have an inverse function to convert a feraction to a decimal?

Yes, you hit the yellow 2nd key and then the back arrow (it says F D above it in yellow.) It's the last key on the bottom of the left hand row.

Hi,

To do this on any calculator, enter the numerator and denominator of your mixed fraction, with a divide in between. I get 1.4. Next, take the decimal into a fraction and reduce it to lowest terms. In this case, 0.4 converts to 4/10 which reduces to 2/5. Putting the two pieces together, we get 1 and 2/5.

Good luck.

Paul

Just divide the numerator by the denominator. For example, to convert 1/4 to decimal, press 1 / 4 ENTER and see .25

You can do that only if the decimal part (the part after the decimal point) is exactly 0. Anything else will be a rational number { a fraction with integer numerator and denominator}

To force the calculator to display a result as a decimal number, try putting a decimal mark at the end of a numerator or denominator. If you are using radicals, put a decimal point at the end. Example: enter square root of 2 as SQRT(2.). Notice the decimal mark at the end of 2.

You will readily agree with me that there is surer source of information than the guide book. Here is a link to it.

There isn't one. If you want to convert a value from decimal to fraction, use the >Frac function (press MATH 1). If you want to enter a fraction, simply enter the numerator, divide, then the denominator.

For example, to calculate 1/4 + 1/3, press

( 1 / 4 ) + ( 1 / 3 ) MATH 1 ENTER

and you'll see 7/12.

Transforming 0.175 to fraction:

= 175/1,000

Reduce to lowest term (divide by 5 both the numerator and the denominator):

= 35/200

Reduce further by dividing both by 5:

= 7/40

This is the lowest terms now that it can't be reduced further.

The "Other" way round, Bottom number into ONE and multiply it by the Top. EG: 3/4 == 1 divided by 4 = 0.25, now we multiply, .25 by the Top number or in this case 3, that equals 0.75. 1/4 =0.25 x 3 = .75. 3/4 is the same as 0.75.

= 175/1,000

Reduce to lowest term (divide by 5 both the numerator and the denominator):

divide the numerator by the denominator

Here is one solution. You might consider adding more robust error handling.

if the decimal numbers passed to the div function are multiples i will be a non-zero number of that multiple otherwise i will be zero.

Dim i As Integer

i = div(12, 0)

If i = 0 Then

'not multiple

' do this

Else

' is multiple

' do something else

End If

Function div(ByVal numerator As Object, ByVal denominator As Object) As Integer

dim n , d decimal

Dim result As Decimal

Dim remainder As Decimal

If IsNumber(numerator) Is True _

And IsNumber(denominator) Is True Then

If numerator <> 0 Then

n = numerator

d = denominator

Else

GoTo error1

End If

Else

GoTo error1

End If

result = Decimal.divide(n, d)

remainder = Decimal.remainder(n, d)

If remainder = 0 Then

div = result

Else

div = 0

End If

Exit Function

error1:

msgbox("Numbers must be non-zero numerics", , "Multiple check error")

div = 0

End Function

End Function
