Find the LCM of denominators, 7 is the LCM of 7 and 1. Multiply the LCM 7 with all the numerators and denominators of both fractions (12/7 x 7/7) - (6 x 7/7) and simplify further in order to have the common denominators. By simplifying the fraction subtraction expression becomes -30/7.
The below workout with step by step calculation shows how to find the difference between fraction and a whole number by subtracting 6 from 12/7. use any one of the following methods to find the equivalent fraction for 12/7 minus 6.
1. LCM method
2. Cross multiplication method.
12/7-6 using LCM Method:
What is 12/7 minus 6 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 12/7
Fraction B: 6/1
What to be found?
12/7-6 = ?
Find what's the difference between 12/7 and 6.
step 2 Compare the denominators of fractions 12/7 and 6 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 12/7 and 6 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 12/7 and 6:
The LCM of 7 and 1 is 7.
step 4 Write the fractions 12/7 and 6 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=12/7-6
=(12 x 7)/(7 x 7)-(6 x 7)/(1 x 7)
step 5 Simplify the expression to have common denominator:
=12/7-42/7
step 6 Take the common values out and rewrite the above expression like the below:
=1/7 x (12/1-42/1)
=1/7 x (12 - 42)
step 7Simplify the above expression further:
=1/7 x -30
=-30/7
12/7-6=-30/7
Hence,
12/7 minus 6 equals to -30/7 in fraction.
12/7-6 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 12/7
Fraction B: 6/1
What to be found?
12/7-6 = ?
Find what's the difference between 12/7 and 6.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (12 x 1), find the product of numerator of Fraction B and denominator of Fraction A (6 x 7), and find the product of both denominators of Fraction A and Fraction B (7 x 1) and rewrite the equation as like the below:
= (12 x 1) - (6 x 7)/(7 x 1)
step 3 Simplify and rewrite the fraction:
= (12 - 42)/7
12/7-6 = -30/7
Hence,
12/7 minus 6 = -30/7
