### How do I change a percentage to a fraction

OR to work it out yourself.....#

### How to convert percent to fraction

1. Divide the percent by 100 to get decimal number.
2. Count the number of digits (d) to the right of the decimal point of the decimal number.Example: 2.56 has 2 digits to the right of the decimal point, so d=2.
3. Calculate the factor (f) for making the decimal number an integer: f = 10 to power d
Example:
f = 10 power 2 = 100
4. Multiply and divide the decimal number x by the factor f: x * f / f = y / f
Example:
2.56 * 100 / 100 = 256 / 100
5. Find the greatest common divisor (gcd) of the fraction. Example:
gcd(256,100) = 4
6. Reduce the fraction by dividing the numerator and denominator by the gcd value: Example:
256 / 100 = (256/4) / (100/4) = 64/25
Example One percent is equal to one hundredth:
1% = 1/100
So in order to convert percent to fraction, divide the percent by 100% and reduce the fraction.
For example 56% is equal to 56/100 with gcd=4 is equal to 14/25:
56% = 56/100 = 14/25

### Need to change my display from a comma to decimal

I don't know which particular calculator model you have, but for an HP-12C, the manual says the following:
Digit Separators
As a number is keyed in, each group of three digits to the left of the decimal point is automatically separated in the display. When the calculator is first turned on after coming from the factory - or after Continuous Memory is reset - the decimal point in displayed numbers is a dot, and the separator between each group of three digits is a comma. If you wish, you can set the calculator to display
a comma for the decimal point and a dot for the three-digit separator. To do so, turn the calculator off, then press and hold down the [.] key while you press [ON]. Doing so again sets the calculator to use the original digit separators in the display.

### How do i configure this calcualtor to round to multiple decimals and not the 2 decimal places it defaults to?

Use the middle slide switch of the three between the display and the keyboard.

The far left position sets it to two decimals, the far right position displays all effective digits up to twelve, the inner positions allow you to specify the number of decimal digits.

If you need a manual, you can download one from the manufacturer's web site at

### I am trying to find a way to use my calculator and its financial functions but i have no idea how. i need the present value of \$1 and present value of annuity of \$1

Neely Neel Neel Neelerson,

--> APPS
--> TVM

Viola. The initials TVM stand for Time-Value-Money; it's a widely used tool throughout financial mathematics. If you are looking to deal with annuities, bonds, present value equations, future value equations, or even certain stocks then you will want to use the TVM app within your TI-84.

When you go into that menu screen you will see about 10 input lines; and despite how you're being taught you'd be best off using only five (from a mathematical & conceptual standpoint). The backbone of the TVM is the time-zero equation of value. So, all you want to be touching is the N, I/Y, PV, PMT, and FV keys.

Background on TVM:
N = Number of intervals
I/Y = Effective Interest Rate Per Interval (5% is .05 but the computer wants it entered as 5.0)
PV = The Present Value
PMT = Recurring Payment (either deposit or withdrawal)
FV = Future Value

There are like 3 other inputs that I encourage you to ignore (in exchange for learning exactly what's going on within this application).

NOTE: You MUST make your effective interest term match your number of intervals. For example, an annuity with monthly payments for 5 years with a monthly effective interest rate of 2% would need an N value of 60 (which is 12 months per year times 5 years for a total of 60 months).

There's more that could be said, but I think this should help you find the PV of an annuity.

### Iit mathematics questions 2+3=24, 7+2=30, 6+5=72, 8+4=65 then 9+7=?

a + b = (a+b+1) x (b+1)
2 + 3 = 24 : (2+3+1 x 3+1)
7 + 2 = 30 : (7+2+1 x 2+1)
9 + 7 = 136

### DISPLAYS 6.599743591E-4 - WHAT'S THAT?

Hello,
I am as surprised as you are, but not by the number. Usually people who dare to handle this calculator know something about scientific notation and higher mathematics.
No matter. What is displayed is a number cast in scientific notation the format of which is as follow:
One digit| decimal mark| 0 to 9 decimal digits| E | a - sign, or no sign| one or more digits.

The part before the E is called the mantissa.
E is a shorhand notation for times 10 to the power
The rest is the exponent. The exponent can be negative or positive and the number between 0 and 99, except for some avanced HP calculators that can display numbers up to 1E 500.

6.599743591 x 10^(-4) or 0.0006599743591

By the way, this is a fine calculator and still the top of the line of TI calculators for engineering, mathematics and science. Take good care of it.

Hope it helps.

### I just replaced the batteries in my HP 12C calculator and when I turned it back on the display looks like this 0,000. How do I get the display to show decimals instead of a comma?

Hello,
Here is what the manual for the HP 12C Platimum financial calculator says on page 17 of 275

Digit Separators
As a number is keyed in, each group of three digits to the left of the decimal point is automatically separated in the display. When the calculator is first turned on after coming from the factory — or after Continuous Memory is reset — the decimal point in displayed numbers is a dot, and the separator between each group of three digits is a comma. If you wish, you can set the calculator to display a comma for the decimal point and a dot for the three-digit separator. To do so,
turn the calculator off, then press and hold down the [ . ] key while you press [ON] Doing so again sets the calculator to use the original digit separators in the display.

### Combinations and Permutations

You can enter combinations and permutations.

If the order of the selection matters (ie. 1st, 2nd, and 3rd place out of 40 contestants) use permutation. Enter:

IF order doesn not matter (ie. a team of 3 from 40 possible members) then it is a combination. Do the same as above, but substitute {nCr} for {nPr}. (= 9880 possible ways).

For your question: a three-digit set, selecting from 0-9. There is no specified order, it is a combination. The total n=10 (there are 10 digits in the range 0-9) and you are selecting 3.

so.... 10[nCr]3 with give the number of possible combinations.
