That is the answer in fraction representation. If you want to convert it to decimals use the [S<->D] key. Every time you press that key the displyed result changes to the other form.

Hope it helps.

Write 156/39 in simplest form

The trick I use is to add up the digits of each number.

1+5+6 = 12, 1+2 = 3
3+9 =12, 1+2 = 3
Now since both numbers add up to 3 or a multiple of 3, they are divisible by 3. (If both added up to 9, both would be divisible by 9).

So let's divide top and bottom by 3.

156 /3 = 52
39/3 = 13

The number 13 is prime, so we cannot reduce it any more. However, 4 x 13 is 52, so we can divide top and bottom by 13.

52/13 = 4
13/13 = 1
Thus, our answer is 4.

This is the longer (and always works version).

We could take 156 / 39 and get 4. We could take 39/39 and get 1 to get our answer of 4/1 or 4, but the numbers are too big for my brain to do that;)

Good luck,

What is the rolling offset using 45 deg bends

The formula for 45 degree bends is offset" x 1.414 equals the travel distance in inches. Example: to calculate the offset of a line 6 1/4", in other words move the line over. Turm 1/4 into decimal form (1 divided by 4=.25). Calculate: (6.25 x 1.414= 8.8375). To convert the decimal form of .8375 to a fraction multiply it by 16 (16/16=1") example: .8375 x 16=13.4 , 13 is the numerator, 16 is the denominator which gives you a fraction of 13/16". That gives you your travel distance center to center of a 6 1/4" offset= 8 13/16" travel distance. For accuracy in your measurement, you must subtract the fitting allowance (how much space the fittings take up in the measurement) from your overall travel distance. It sounds like a lot of steps, but using this formula gives you dead on accuracy in pipe fitting. If you know your travel distance and wish to find the offset, multiply x .707. Hope this helps.

How to find G.C.F. on a TI-30xIIs calculator?

I don't think there's specific key for this but you can do it this way:

  1. Divide those 2 numbers for which you want to find gcf
  2. If you get result as decimal number press keys [2nd][PRB] to display it as fraction
  3. Also if fraction you get is in form a b/c (ex. 1 2/3) you have to convert it to form d/c (for 1 2/3 that would be 5/3)
  4. Greatest common factor is then 1st number divided by numerator (or 2nd number divided by denominator)
For example:
  • You want to find greatest common factor of 30 and 18.
  • You divide them: you should get 5/3 (after converting result to fraction of form d/c, as described in steps 2 and 3).
  • This means that 30/18=5/3=5x/3x (x is gcf here).
  • Now you know that x=30/5=18/3=6 so greatest common factor is 6.

I hope this helps :)

Whenever i do a large sum, for example 102795/600,...

Let us first set the record straight: Your calculation is a division not an addition. Be it as it may, the result you obtain is correct the fraction is equivalent to the one you entered, the difference lie in the fact that the calculator reduces the (entered) fraction to its simplest form.
Both the numerator and the denomonator have been divided by 15.

If the result is already calculated and displayed, press the [S<=>D] key It will convert a fraction or radical to decimal. This is always possible. If the result is decimal it may be converted to a fraction or a radical (Not always possible).

If the expression to be evaluated is still in the command line and you have not pressed the [=] key, you can force the result to be displayed in decimal format by pressing [SHIFT][=] instead of just [=].

More permanently. If you do n o care for fractions and radicals, set the Input/Outpout mode to LineIO. To do do press [SHIFT][MODE] to access the (SETUP) screen and select [2:LineIO]

When I divided a problem EX. 3/2 the calculator will not answer in decimal

You are not dividing problems, you are dividing number. This said, there is a simple way to ensure that the results of divisions are displayed in decimal form: It consists in putting a decimal mark (decimal point) at the end one integer (whole number)
3/2. gives 1.5
3./2 gives 1.5
3./2. gives 1.5

You can also configure your calculator to display all numerical results in decimal format. To do that press [MODE][F2]. Use the down arrow to select the ligne Exact/Approx, then use the right arrow to unfold the menu options 1:Auto
Select 3:Approximate and press [ENTER]

Hope it helps.

When I divide the answer is in fraction form not decimal form how do i get it back

There are two options.

1) Whenever you want the answer in decimal form, place a decimal after at least one of the numbers.
For example: instead of using (1/2) use (1/2.)

2) Press the "Mode" button. Scroll down the list that appears until you find "Exact/Approx". If you set it to "Approximate", then it will always give the answer in decimal form. If you set it to "Exact", it will give the answer in fraction form.

When I try to divide numbers that would leave a remainder like 1 divided by 6 which should give me an answer like 0.16666666666 instead all it says for an answer is 1/6. it does say in the manual to input...

To convert from fractions to decimals, and from decimals to fractions use the [S<-->D] key. If you want your decimal results to have a fixed number of decimal places press [SHIFT][SETUP][6:Fix]. Screen shows Fix 0~9. Enter the number of decimal places exemple 3.
Dans ce cas 1/6 is displayes ase 0.167.
Hope it helps.

Log function help

Sorry, this might not be much help but apparently the calculator is set in a mode called "base 10".  I have never learned logrithms really in school, but did a little for my ACT.  I figured that in order to do a problem, you need to divide.  EXAMPLE: 8 log 2 = ? would be entered [log] [8] / [log] [2] [EXE] and the answer 3 will be displayed.  Not much help, but maybe this will get you in the right direction.

Mixed numbers

Proper fraction e.g. 3/5, input 3, divide, 5, =, answer 0.6

Improper fraction, either enter as improper fraction, or enter the whole number first, then +, then the proper fraction as before, then =.

E.g. 8/5 which is "1 and 3/5': enter 1, +, 3, "divide", 5 =, answer is 1.6

Or, just 8, "divide", 5, same 1.6 answer. Why go to mixed number first?

13/5 which is "2 and 3/5", enter 2, +, 3, "divide", 5, =, answer is 2.6. Or, just 13/5, same answer

How do I on a TI-84 Plus Simplify Fractions

Enter the fraction for example: enter 8/12.
The answer will be .666666
Then click Math (which is located under the Alpha button).
Click the ->Frac button (the first one).
It should come up as Ans->Frac.
Click Enter.
It should now read 2/3 which is 8/12 reduced.
Note: I have a TI-84 Plus Silver Edition, and the TI-84 Plus might not have this function, but that is how I do it on my TI-84 Plus Silver Edition
