How to divide 1 2/3 by 3


First make 1 2/3 into a mixed fraction and then divide it by 3.
To make 1 2/3 into a mixed fraction, multiply the whole number, in this case, 1, by the denominator (the bottom number) and then add the numerator (the top number). Thus, we get (1*3+2)/3 or 5/3. Now we have to take 5/3 and divide it by 3. I was taught that in this case, dividing by 3 is the same as multiplying by 1/3. 5/3 x 1/3 = 5/9.

If you have access to a calculator you can always check this. On the calculator, do 2 divided by 3 and add 1. Now take that answer and divide by 3. Write down this answer. Now take 5 and divide by 9. Write down this answer. They should be the same.

Good luck.

How to compute fraction multiplication?


Multiply the numerators (the top numbers) and multiply the denominators (the bottom numbers).

As an example, 3/4 x 4/5 = (3 x 4)/(4 x 5) = 12/20. Now we should reduce it to lowest terms by dividing numerator and denominator by the greatest common factor. I divided the numerator and denominator by 4 and got 3/5.

Good luck.

Can you help me on this question?


This answer is correct. 4/12 divided by 2/2= 1/3
The reciprocal of 2/2 is 2/2
Then you multiply straight across and reduce to get 1/3

How does dividing mixed numbers compare with dividing fractions?


This may not be what you want, but I turn the mixed number into a fraction. Say 5 1/2, you multiply the whole number (5) by the denominator for the fraction (2), then add the numerator. So you have 5X2+1. That is the new numerator, it goes over the denominator. This gives you 11/2. To check it divide the numerator by the denominator. 2 into 11 gives you 5 (Rem) 1. 1 is the numerator now and it goes over the denomerator. 5 1/2.
I know it sounds like a lot, but try about ten or so, it becomes 2nd nature. You can make it all into decimal, 5 1/2 becomes 5.5, but now you have to put more numbers into the equation.
This is true. I had a math teacher ask me if he had to cut down a tree so I'd have enough scratch paper.

How do i do - 5/8 - 2/7


Hi Molly, get the denominators to be the same by multiplying then multiply the numerators by the same - so 7x8=56 and 7x5=35 = 35/56 and 8x7=56 and 8x2=16 = 16/56 so the sum is 35/56 - 16/56 = 19/56

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

4 - 4 - 4 - 4 =20 put mathematic signs (+,-,*,/) in the blanks and try to find a correct way.


This is the classic "Four Fours" problem. Combine the four fours as
4 / 4 + 4 * 4 with the operations taking place from left to right. The first 4 divided by the second produces 1. Add the third 4 to produce 5. Multiply by the fourth 4 results in 20.

Explain 1 divided by 0


In mathematics, a division is called a division by zero if the divisor is zero. Such a division can be formally expressed as a / 0 where a is the dividend. Whether this expression can be assigned a well-defined value depends upon the mathematical setting. In ordinary (real number) arithmetic, the expression has no meaning, as there is no number which, multiplied by 0, gives a (a?0).
In computer programming, an attempt to divide by zero may, depending on the programming language, generate an error message or may result in a special not-a-number value (see below).
Historically, one of the earliest recorded references to the mathematical impossibility of assigning a value to a / 0 is contained in George Berkeley's criticism of infinitesimal calculus in The Analyst; see Ghosts of departed quantities.

Calculations in Adobe 8.0


Are you using live cycle (Part of Adobe 8)
On the RAW form - select from main bar - Window, Script Editor

Your Addition or Subtraction will be :
Field 1 + Field 2 or Filed 1 - Field 2
For division, change this to Field1 / Field2
For multiplication, Field1 * Field2

I have a PDF (Created in Livecycle that calculate standard deviation in tabular format) - currently working on the graphical representation
