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.

### How do I get the TI-85 to convert an improper fraction to a mixed number?

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.

### How do I convert a decimal into a whole number?

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}

### Fraction to decimal function not working,only reducing decimals not converting them to fractions when using proper 2nd function option

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.

### Hello where is the fraction button on the ti-84 plus silver edition

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.

### Convert

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.

### Need help in Special Formatting Number

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
