Question

hey can some one tell me rules of reducing a fraction ... I was also facing a problem with the term 'common nikal ' I can't understand what it means plz give example ..
also how is multiplication of fraction is done when there are two alike fraction ... 30 points for 3 questions ☺

Answer 1

Reducing Fractions To Their Lowest Equivalent
Here’s the Rule for simplifying or reducing fractions to their lowest term…

Fraction Rule
Always keep in mind…

Whatever you do to the numerator of a fraction you must also do to the denominator. So if you have to divide the numerator by a number, you must also divide the denominator by the same number. That way you will not change the overall value of the fraction.

In our rule, we have divided the numerator and the denominator by “c” to arrive at our simplified answer.

Here’s the situation. You have added the fractions okay, but your answer may not be showing the lowest equivalent fraction. The easiest way to know for sure that your answer is in its simplified form is to breakdown both the numerator and the denominator into prime numbers.

This process is called Prime Factorization.

Here’s an example so you’ll get the idea…




Notice that the original answer after adding the fractions is “2/4.” To determine if our answer is in its simplified form, we must factor the numerator and the denominator into its prime numbers.

What we are looking for are the prime numbers that are common to both the numerator and the denominator. If we find these common numbers, we can then cancel them out. The results will be a fraction simplified to its lowest equivalent fraction.

Since “2” is a common factor in both the numerator and denominator of our example above, it indicates that our answer is not in its simplest form. Therefore, we cancelled out (/)one of the 2’s in both the numerator and denominator by dividing by “2”, one for one. The results is a “simplified fraction” reduced to its lowest term.

Answer 2

Its a very simple task..

Just take an example suppose

(20x+40)/2

Here you cant divide the equation till u know the value of x.

So take out the common number from numerator which u can divide from denominator i.e., 2

Common nikala 20 so eqn wud be

20(x+2)/2=10(x+2)

Nd plz explain ur 3rd question nicely cant get it properly..

Hope it helps u...
