By simplifying the fraction subtraction expression becomes -9/42.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 12/7 from 9/6. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 9/6 minus 12/7.
1. LCM method
2. Cross multiplication method.
9/6-12/7 using LCM Method:
What is 9/6 minus 12/7 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 9/6
Fraction B: 12/7
What to be found?
9/6-12/7 = ?
Find what's the difference between 9/6 and 12/7.
step 2 Compare the denominators of fractions 9/6 and 12/7 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 9/6 and 12/7 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 9/6 and 12/7:
The LCM of 6 and 7 is 42.
step 4 Write the fractions 9/6 and 12/7 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=9/6-12/7
=(9 x 42)/(6 x 42)-(12 x 42)/(7 x 42)
step 5 Simplify the expression to have common denominator:
=63/42-72/42
step 6 Take the common values out and rewrite the above expression like the below:
=1/42 x (63/1-72/1)
=1/42 x (63 - 72)
step 7Simplify the above expression further:
=1/42 x -9
= -9/42
=-3/14
9/6-12/7=-3/14
Hence,
9/6 minus 12/7 equals to -3/14 in fraction.
9/6-12/7 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 9/6
Fraction B: 12/7
What to be found?
9/6-12/7 = ?
Find what's the difference between 9/6 and 12/7.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (9 x 7), find the product of numerator of Fraction B and denominator of Fraction A (12 x 6), and find the product of both denominators of Fraction A and Fraction B (6 x 7) and rewrite the equation as like the below:
= (9 x 7) - (12 x 6)/(6 x 7)
step 3 Simplify and rewrite the fraction:
= (63 - 72)/42
= -9/42
= -3/14
9/6-12/7 = -3/14
Hence,
9/6 minus 12/7 = -3/14
