Let's do some examples.

4 x 6 = 24 (four groups with six in each group)

4 x 6/10 = 4/1 x 6/10 = 24/10 = 2.4 (multiply the numerators and multiply the divisors)

Good luck,

Paul

How to solve franctions


Multiplying Fractions:
  1. Make sure you're working with two fractions.
  2. Multiply numerator x numerator, then multiply denominator x denominator.
Dividing Fractions:
  1. Make sure you're working with two fractions
  2. Flip the second fraction upside down.
  3. Change the division sign into a multiplication sign.
  4. Multiply top x top and bottom x bottom.
Converting Mixed Numbers into Improper Fractions:
  1. Convert mixed numbers into improper fractions.
  2. Take the whole (non-fraction) number and multiply it by the denominator.
  3. Add that answer to the numerator.
  4. Put that amount over the original denominator and you will have an improper fraction.
Method for Adding and Subtracting Fractions:
  1. Find the lowest common denominator (bottom number). For both adding and subtracting fractions, you'll start with the same process.
  2. Multiply fractions to match the lowest common denominator.
  3. Add or subtract the two numerators (top number) but NOT the denominators.

What is a reciprocal


(mathematics) one of a pair of numbers whose product is 1: the reciprocal of 2/3 is 3/2; the multiplicative inverse of 7 is 1/7
The reciprocal of a number is the quotient obtained by dividing one by the number. Thus the reciprocal of 8 is 1/8. Applied to fractions the above operation is carried out by simply inverting the fraction. Thus the reciprocal of 3/4 is 4/3 or 1-1/3.
As if math wasn't hard enough without this, huh?
I hope this was of some help to you. Good luck,
Bill

Formula for converting fractions into percentage.


Simplest method
  1. divide the top of the fraction by the bottom
  2. Then multiply the result by 100
  3. add a percent sign to the answer so people know it is a percentage (i.e. per 100)
  • e.g. 3/5 *100 = 0.6 * 100 = 60%

Alternative method Since percent means "per 100", you can try to convert the faction to the form ?/100
follow these steps:
  1. find a number that you can multiple the bottom of the fraction by to get 100
  2. multiple both top and bottom of the fraction by that number
  3. write down just the top number with the % sign added to the end
  • e.g. 3/5 as a percentage
  1. we can multiply 5 x 20 to get 100
  2. multiple top and bottom by 20 = (3*20)/(5*20) = 60/100 = 60%

I hope this helps and good luck! If you have more questions - ask away! Please take the time to rate this answer.

How do you put in a fraction to mulitiply it by another fraction?


A fraction is just a particular number.
  1. Enter numerator of first fraction
  2. Press the division sign
  3. Enter the denominator of first fraction
  4. Press the multiplication key
  5. Enter second numerator
  6. Press the division key
  7. Enter the denominator of second fraction
  8. If you want a decimal result press [ENTER]
  9. However, if you want a fraction press [MATH][1:

I try to write a fraction down on my TI-83 calc. But i dont know how to find that function. When i go to MATH and choose FRAC it doesnt do anything even if i type a number down next to it.


To keep a fraction in fraction format (though reduced) you must enter the numerator, press the Division key, followed by a number (denominator).

If you press ENTER, the fraction will be displayed as a decimal number.
However if you use the sequence [MATH][1:ToFrac] peior to pressing [ENTER] the result will be the irreducible form pf the fraction you entered.
Obviously, if you enter an interger number there will not be any fraction display.
Also, if your "number down next to it" means after the [ToFrac], then it is clear that nothing will happen.

Try what I suggest and see if that works.

Okay,when i push shift then push d/c,it don't work? I am not sure if I am doing it in a wrong order or what?


If you want to enter an improper fraction, you enter it with the [a b/c] key as follows
numerator [a b/c] denominator.
If you want to enter a mixed fraction do as follows
interger [a b/c] numerator [a/c] denominator
If you want to convert a mixed fraction to an improper fraction use the key sequence [2nd or SHIFT] [d/c]

I cant seem to find how to make a simple fraction on the TI-30X2S


Hello,

To enter fraction 2 1/3 use the sequence 2 [a b/c] 1 [a b/c] 3 [=].
Separate the interger, the numerator, and the denominator with the key [a b/c].

Hope it helps.

Simplifying fractions on the TI-30XA


Two ways:

1) hit the equal sign

2) hit 2nd and [d/c] (you can do this multiple times to see it as the most reduced improper fraction or as a mixed fraction)

Motherboard Intel D101GGC no display


Hello dheyx, your Intel D101GGC board used an intergated ATI Radeon Xpress 200 graphics. If you lost display than you're intergated Radeon has died. Suggest you replace it with a
PCI-E X16 graphics card. The Intel D101GGC board does have an opened X16 PCI-E slot. Do not forget to change the bios video card setting. You want the board to see& load the PCI-E first.

I think the F-D function only works one direction from fraction to decimal. Decimal to fraction is a non trivial calculation that can have multiple answers so doesn't lend itself to a calculator feature.
