Learn how to find what is 2/7 minus 4/6 in fraction form just in a few minutes. We have covered the easiest method to write 2/7 - 4/6 as a fraction and decimal.
Summary: 2/7 minus 4/6
Since both the fractions have the unequal denominators, you have to find the equivalent fractions for 2/7 and 4/6 having identical denominators before starting adding the fractions. Find the LCM of denominators, 42 is the LCM of 7 and 6. Multiply the LCM 42 with all the numerators and denominators of both fractions (2/7 x 42/42) - (4/6 x 42/42) and simplify further in order to have the common denominators. By simplifying the fraction subtraction expression becomes -16/42.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 4/6 from 2/7. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 2/7 minus 4/6.
1. LCM method
2. Cross multiplication method.
2/7-4/6 using LCM Method:
What is 2/7 minus 4/6 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/7
Fraction B: 4/6
What to be found?
2/7-4/6 = ?
Find what's the difference between 2/7 and 4/6.
step 2 Compare the denominators of fractions 2/7 and 4/6 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 2/7 and 4/6 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 2/7 and 4/6:
The LCM of 7 and 6 is 42.
step 4 Write the fractions 2/7 and 4/6 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=2/7-4/6
=(2 x 42)/(7 x 42)-(4 x 42)/(6 x 42)
step 5 Simplify the expression to have common denominator:
=12/42-28/42
step 6 Take the common values out and rewrite the above expression like the below:
=1/42 x (12/1-28/1)
=1/42 x (12 - 28)
step 7Simplify the above expression further:
=1/42 x -16
= -16/42
=-8/21
2/7-4/6=-8/21
Hence,
2/7 minus 4/6 equals to -8/21 in fraction.
2/7-4/6 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/7
Fraction B: 4/6
What to be found?
2/7-4/6 = ?
Find what's the difference between 2/7 and 4/6.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (2 x 6), find the product of numerator of Fraction B and denominator of Fraction A (4 x 7), and find the product of both denominators of Fraction A and Fraction B (7 x 6) and rewrite the equation as like the below:
= (2 x 6) - (4 x 7)/(7 x 6)
step 3 Simplify and rewrite the fraction:
= (12 - 28)/42
= -16/42
= -8/21
2/7-4/6 = -8/21
Hence,
2/7 minus 4/6 = -8/21
