5/7-7/14 using LCM Method:
What is 5/7 minus 7/14 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 5/7
Fraction B: 7/14
What to be found?
5/7-7/14 = ?
Find what's the difference between 5/7 and 7/14.
step 2 Compare the denominators of fractions 5/7 and 7/14 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 5/7 and 7/14 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 7/14:
The LCM of 7 and 14 is 14.
step 4 Write the fractions 5/7 and 7/14 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=5/7-7/14
=(5 x 14)/(7 x 14)-(7 x 14)/(14 x 14)
step 5 Simplify the expression to have common denominator:
=10/14-7/14
step 6 Take the common values out and rewrite the above expression like the below:
=1/14 x (10/1-7/1)
=1/14 x (10 - 7)
step 7Simplify the above expression further:
=1/14 x 3
=3/14
5/7-7/14=3/14
Hence,
5/7 minus 7/14 equals to 3/14 in fraction.
5/7-7/14 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 5/7
Fraction B: 7/14
What to be found?
5/7-7/14 = ?
Find what's the difference between 5/7 and 7/14.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (5 x 14), 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 14) and rewrite the equation as like the below:
= (5 x 14) - (7 x 7)/(7 x 14)
step 3 Simplify and rewrite the fraction:
= (70 - 49)/98
= 21/98
= 3/14
