Find the lowest number the 9 and 6 will divide into (the lowest common denominator). In this case, it is 18 (9X2 and 6X3). Therefore 2/9 + 2/6 = 4/18 + 6/18 which totals 10/18---which, if both numbers are divided by 2, also equals 5/9.

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

To enter your equation press 12 then a/b (the fraction key). 12 will now be at the top of your fraction and there will be an arrow blinking in the bottom block. then press 2. If the part in brackets is also meant to divide into 12 then simply press open bracket ( 6 - 7 + 4 close bracket ) right arrow to get out of the fraction and then x 2. If the part in brackets is not meant to be divided into 12 then press the right arrow key before typing in the open bracket ( 6 - 7 + 4 etc.

OK It is a little difficult trying to figure out the fractions you are trying to describe. Are there 3 fractions within the ( ) ? One with a denominator of 3, one with a denominator of 4, and one with a denominator of 6?

If so, the answer is 9q.

You must change the fractions within the ( ) to a common denominator, which would be 12. That would be 8q+3q-2q all over 12. Since it is all being multiplied by 12 outside the brackets, you just cancel the 12 outside and the 12 denominator inside which leaves the 8q+3q-2q which equals 11q-2q which equals 9q.

Thanks for using Fixya.

To do fractions, input like this:
(1/3)+(4/9)
Granted the answer is a decimal... But you should be able to convert that to a fraction using what you've learned in math class.
PI sign: Just press [2nd]and then[^]. And voila, instant π! Exponent:enter more complicated expressions involving exponents using parentheses and the negative sign.

Check all the Marks with IF Function if Mark is less than 35 give the total mark else give the rank
for Ex:;
if(Or(m1<35,m2<3,m3<35,.....),TotalMark,Grade)) [enter]
here m1,m2,m3 ...are the cells denoting Marks, Totalmark is the cell Showing total marks and Grade is the grade applied for the condition. here also you can use one more if function to find the grade among A,B,C,D,E
First this function check whether any of the given marks are less than 35. if any of the marks is less than 35 it will get the answer TRUE for the OR Function and you will get the Totalmark Cell VAlue, else it will go to Grade Clause.

In Math Mode, press shift then equals will change the fraction result to a decimal result

type the whole number then hit the ABC button then type the numerator then hit ABC then type the denominator


1ABC1ABC2 + 1ABC1ABC2=3
