Reducing Fractions

Perry Said:

reducing fractions?

We Answered:

I would need to see actual problems. Remember, some fractions cannot be reduced. Any fraction that can be reduced, you must use the highest # that goes into both numbers. Also, when multiplying fraction, you flip the second set of numbers and if you have two sets of the same # (diagonal only) then you cross cancel them and make them a 1.

How to factor and reducing fractions?

We Answered:

Factoring:
This is a difference of two cubes: (a - b)(a^2 + ab - b^2)

Take the cube root of 8x^3 and you get 2x, which will be ''a''
take the cube root of 1 and you get 1, which will be ''b''

plug in numbers 2x for ''a'' AND 1 for ''b''

(2x - 1)(4x^2 + 2x - 1)

Second question : what x can NOT be:

Factor the denominator:
x^2 - 3x - 10
(x - 5)(x + 2)

Set the factors equal to 0 (zero) and solve for x:

x - 5 = 0
x = 5

x + 2 = 0
x = -2

x can NOT be 5 or -2 because if they were, you'd get a 0 (zero) in the denominator and you can't do that!

Ray Said:

What is the easiest way to learn prime factorization and apply it when reducing fractions to their lowest term

We Answered:

My method is if the numerator and denominator are both even numbers, cut it in half. If they are still evens, cut it again. If you can sum the digits in both the numerator, sum the digits in the denominator, and they both total a number divisible by 3, divide each by 3.

If there's a 5 or a 0 in both, you can divide both by 5. Usually this will do it. You may want to test 7, 11, 13 on both if you're really not sure.

So you keep going until you get low enough to see for yourself it can't get any lower.
