Simplify 9/12 to its Simplest Form
In order to simplify the fraction 9/12, we will follow below steps.
Step 1:
To simplify 9/12 in its simplest form, let us divide both the numerator 9 and the denominator 12 by their greatest common divisor (GCD).
Step 2:
Now, we will find the GCD of 9 and 12.
- The divisors of 9 are 1, 3, and 9.
- The divisors of 12 are 1, 2, 3, 4, 6, and 12.
Therefore, 3 is the highest number that divides both 9 and 12. So the greatest common divisor of 9 and 12 is 3. That is,
GCD (9, 12) = 3.
Step 3:
Divide the top and the bottom by GCD (9, 12) = 3.
$\dfrac{9}{12} = \dfrac{9 \div 3}{12 \div 3} = \dfrac{3}{4}$.
So the fraction 9/12 simplified in its simplest form is equal to 3/4.
How to Simplify the Fraction 9/12
The video solution on how to simplify 9/12 is provided below:
Reduce 9/12 to its Lowest Term
To reduce 9/12 in its lowest terms, at first we write down the prime factorisations of 9 and 12.
9 = 3 × 3
12 = 2 × 2 × 3
Therefore,
$\dfrac{9}{12} = \dfrac{3 \times 3}{2 \times 2 \times 3}$
⇒ $\dfrac{9}{12} = \dfrac{3 \times \cancel{3}}{2 \times 2 \times \cancel{3}}$, here we cancel the common number 3.
⇒ $\dfrac{9}{12} = \dfrac{3}{2 \times 2} = \dfrac{3}{4}$
So the fraction 9/12 reduced in its lowest term is equal to 3/4.
FAQs
Answer: 9/12 simplified as a fraction is equal to 3/4.
Answer: The greatest common divisor (GCD) of 9 and 12 is GCD(9, 12) = 3. To simplify 9/12, divide the top 9 and the bottom 12 by their GCD. Thus, 9/12 = (9 ÷ 3)/(12 ÷ 3) = 3/4. So 3/4 is the simplest reduced form of the fraction 9/12.
