By simplifying the fraction subtraction expression becomes 11/84.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 7/12 from 5/7. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 5/7 minus 7/12.
1. LCM method
2. Cross multiplication method.
5/7-7/12 using LCM Method:
What is 5/7 minus 7/12 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 5/7
Fraction B: 7/12
What to be found?
5/7-7/12 = ?
Find what's the difference between 5/7 and 7/12.
step 2 Compare the denominators of fractions 5/7 and 7/12 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 5/7 and 7/12 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 5/7 and 7/12:
The LCM of 7 and 12 is 84.
step 4 Write the fractions 5/7 and 7/12 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=5/7-7/12
=(5 x 84)/(7 x 84)-(7 x 84)/(12 x 84)
step 5 Simplify the expression to have common denominator:
=60/84-49/84
step 6 Take the common values out and rewrite the above expression like the below:
=1/84 x (60/1-49/1)
=1/84 x (60 - 49)
step 7Simplify the above expression further:
=1/84 x 11
=11/84
5/7-7/12=11/84
Hence,
5/7 minus 7/12 equals to 11/84 in fraction.
5/7-7/12 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 5/7
Fraction B: 7/12
What to be found?
5/7-7/12 = ?
Find what's the difference between 5/7 and 7/12.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (5 x 12), find the product of numerator of Fraction B and denominator of Fraction A (7 x 7), and find the product of both denominators of Fraction A and Fraction B (7 x 12) and rewrite the equation as like the below:
= (5 x 12) - (7 x 7)/(7 x 12)
step 3 Simplify and rewrite the fraction:
= (60 - 49)/84
