Multiply the LCM 12 with all the numerators and denominators of both fractions (9/3 x 12/12) - (8/12 x 12/12) and simplify further in order to have the common denominators. By simplifying the fraction subtraction expression becomes 28/12.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 8/12 from 9/3. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 9/3 minus 8/12.
1. LCM method
2. Cross multiplication method.
9/3-8/12 using LCM Method:
What is 9/3 minus 8/12 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 9/3
Fraction B: 8/12
What to be found?
9/3-8/12 = ?
Find what's the difference between 9/3 and 8/12.
step 2 Compare the denominators of fractions 9/3 and 8/12 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 9/3 and 8/12 are not equal, it is said to be unlike fractions subtraction.
step 3For unlike fractions subtraction, find the LCM (least common multiple) of both denominators of fractions 9/3 and 8/12:
The LCM of 3 and 12 is 12.
step 4 Write the fractions 9/3 and 8/12 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=9/3-8/12
=(9 x 12)/(3 x 12)-(8 x 12)/(12 x 12)
step 5 Simplify the expression to have common denominator:
=36/12-8/12
step 6 Take the common values out and rewrite the above expression like the below:
=1/12 x (36/1-8/1)
=1/12 x (36 - 8)
step 7Simplify the above expression further:
=1/12 x 28
= 28/12
=7/3
9/3-8/12=7/3
Hence,
9/3 minus 8/12 equals to 7/3 in fraction.
9/3-8/12 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 9/3
Fraction B: 8/12
What to be found?
9/3-8/12 = ?
Find what's the difference between 9/3 and 8/12.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (9 x 12), find the product of numerator of Fraction B and denominator of Fraction A (8 x 3), and find the product of both denominators of Fraction A and Fraction B (3 x 12) and rewrite the equation as like the below:
= (9 x 12) - (8 x 3)/(3 x 12)
step 3 Simplify and rewrite the fraction:
= (108 - 24)/36
= 84/36
= 7/3
9/3-8/12 = 7/3
Hence,
9/3 minus 8/12 = 7/3
