How do you divide the denominator into the numerator on the TI-30

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.

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

Enter the numerator and denominator then press Math ToFrac

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.

to change a fraction to decimal on any calculator just press the numbers of the fraction and press either enter or equals.

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
