Explanation:
To express a fraction in
color(blue)"simplest form"simplest form we need to find a number, the largest is preferable, that divides into both 9 and 12.
In this case the largest number that divides into both is 3.Now we divide 9 and 12 by 3
rArr9/12=(9÷3)/(12÷3)=3/4" in simplest form"⇒912=9÷312÷3=34 in simplest form Usually, the task of dividing both numbers by 3 is performed mentally, stroking out the number and replacing it by the value remaining after division.This is called
color(red)"cancelling"cancelling
rArr(cancel(9)^3)/(cancel(12)^4)=3/4
Explanation:
We must first find the largest common factor of the numerator and the denominator. The factors of 9 are 1, 3, and 9. The factors of 12 are 1, 2, 3, 4, 6, and 12. So the greatest common factor of 9 and 12 is 3. So you divide both sides by 3. So the simplest form of
