Today I am going to talk about Reducing Fractions, if you don’t really know what reducing fractions is don’t worry I can explain what it is
.
Reducing Fractions is simplifying a fraction so that the numerator and denominator are both as small as they can possibly be, and the value of the fraction stays the same. For example, 3/6 is the same thing as 1/2 because if you simplify 3/6 by dividing it be three you get 1/2 these are called equivalent fractions. To reduce a fraction you first have to find the greatest common factor of the numerator and the denominator. For example, 12/20 to find the greatest common factor, you can make a list of all the factors of 12 and 20, than pick the biggest one they have in common. So the factors of 12 are 1, 2, 3, 4, 6, and 12, and the factors of 20 are 1, 2, 4, 5, 10 and 20. So the greatest common factor would be 4. To reduce that fraction you divide the numerator and the denominator, by their greatest common factor. 12 divided by 4 is 3 and than 20 divided by 5 is 4. Lets try another one, 4/14 the factors of 4 are 1, 2, 4 and the factors of 14 are 1, 2, 7, 14, looks like the greatest common factor is 2. So the next step is you guessed it the numerator divided by 2 and the denominator divided by 2, so 4/14 equals to 2/7. If you are wondering what if there is no common factors, then it just stay the same.
So I hope you guys learn a little bit about Reducing Fractions
, and also sorry for giving this HUGE load of words.
