What is the improper fraction of 2/10


I think you want to reduce the fraction to the lowest terms.

Improper fraction 1 3/4 produces an improper fraction of 7/4 (1 times denominator plus numerator)

To reduce a fraction, we need to divide the numerator (number on top) and the denominator (number on the bottom) by the greatest common factor (GCF).

To get the GCF, find the factors of the numerators and denominators and find the greatest number that is in both lists.

The factors of 2 are 1, 2.

The factors of 10 are 1, 2, 5, 10.

The greatest (largest) number is both lists is 2, so we divide the numerator and denominator by 2 and get 1/5.

Good luck,

Paul

-54k^2+3k


-54k^2+3k I assume that you want to factor this completely.
I do it one component at a time.
What is the biggest common factor of -54 and 3. I use a trick of adding the digits of the number. If 3 and/or 9 go into that number evenly, than 3 and/or 9, respectively go into the original number. In this case, 5+4 = 9 and since 3 goes into 9 evenly, 3 goes into 54 evenly. Since the factors of 3 are 3 and 1, this must be the greatest common factor of this component.
Onto the next component, what is the greatest common factor of k^2 and k. The answer is k, because k^2 doesn't go evenly into k.
Combining the two, the greatest common factor is 3k.

Next we have to divide 3k into each term.
3k(-18k+1) or -3k(18k-1)

Good luck,

Paul

What is least common factor


Normally, we look for the greatest common factor and the least common multiple.

To find the least common factor, we have to factor both numbers and see what the least common factor is. However, we know the one set of factors for every number is itself and one. For example, 56 and 49.

The factors of 56 are 1, 2, 4, 7, 8, 14, 28 and 56.
The factors of 49 are 1, 7, 49.

What is the least common factor of both numbers? 1

So the least common factor of any two numbers is 1.

Any questions, let me know.

Good luck,

Paul

How can I simplify a fraction after adding two fractions?


Factor both the numerator and denominator, and then divide both the numerator and denominator by the greatest common factor.

For example, 1/3 + 1/6 = 2/6 + 1/6 = 3/6. We have to simplify 3/6. The factors of 3 are 3 and 1. The factors of 6 and 1, 2, 3, and 6. The greatest common factor is 3. Dividing the numerator and denominator by 3 results in 1/2.

Good luck.

Greatest common factors


Please the reformulate the problem(?) with more care. Capital P is a different entity than p. Are you trying to factor out the polynomial (an algebra problem where the Greatest Common Factors have no meaning), or are you trying to find the GCF of certain positive integers (an arithmetic problem)?

Highest common factor


Math is fun has a great article on how to find the GCF of two numbers:

http://www.mathsisfun.com/greatest-common-factor.html

To find the common factors, you have to list all factors of both numbers:
96: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96
124: 1, 2, 4, 31, 62, 124
