Learn how to find what is 3/7 minus 1/6 in fraction form just in a few minutes. We have covered the easiest method to write 3/7 - 1/6 as a fraction and decimal.
Summary: 3/7 minus 1/6
Since both the fractions have the unequal denominators, you have to find the equivalent fractions for 3/7 and 1/6 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 (3/7 x 42/42) - (1/6 x 42/42) and simplify further in order to have the common denominators. By simplifying the fraction subtraction expression becomes 11/42.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 1/6 from 3/7. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 3/7 minus 1/6.
1. LCM method
2. Cross multiplication method.
3/7-1/6 using LCM Method:
What is 3/7 minus 1/6 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 3/7
Fraction B: 1/6
What to be found?
3/7-1/6 = ?
Find what's the difference between 3/7 and 1/6.
step 2 Compare the denominators of fractions 3/7 and 1/6 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 3/7 and 1/6 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 3/7 and 1/6:
The LCM of 7 and 6 is 42.
step 4 Write the fractions 3/7 and 1/6 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=3/7-1/6
=(3 x 42)/(7 x 42)-(1 x 42)/(6 x 42)
step 5 Simplify the expression to have common denominator:
=18/42-7/42
step 6 Take the common values out and rewrite the above expression like the below:
=1/42 x (18/1-7/1)
=1/42 x (18 - 7)
step 7Simplify the above expression further:
=1/42 x 11
=11/42
3/7-1/6=11/42
Hence,
3/7 minus 1/6 equals to 11/42 in fraction.
3/7-1/6 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 3/7
Fraction B: 1/6
What to be found?
3/7-1/6 = ?
Find what's the difference between 3/7 and 1/6.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (3 x 6), find the product of numerator of Fraction B and denominator of Fraction A (1 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:
= (3 x 6) - (1 x 7)/(7 x 6)
step 3 Simplify and rewrite the fraction:
= (18 - 7)/42
3/7-1/6 = 11/42
Hence,
3/7 minus 1/6 = 11/42
