By simplifying the fraction subtraction expression becomes 53/88.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 3/11 from 7/8. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 7/8 minus 3/11.
1. LCM method
2. Cross multiplication method.
7/8-3/11 using LCM Method:
What is 7/8 minus 3/11 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/8
Fraction B: 3/11
What to be found?
7/8-3/11 = ?
Find what's the difference between 7/8 and 3/11.
step 2 Compare the denominators of fractions 7/8 and 3/11 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 7/8 and 3/11 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 7/8 and 3/11:
The LCM of 8 and 11 is 88.
step 4 Write the fractions 7/8 and 3/11 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=7/8-3/11
=(7 x 88)/(8 x 88)-(3 x 88)/(11 x 88)
step 5 Simplify the expression to have common denominator:
=77/88-24/88
step 6 Take the common values out and rewrite the above expression like the below:
=1/88 x (77/1-24/1)
=1/88 x (77 - 24)
step 7Simplify the above expression further:
=1/88 x 53
=53/88
7/8-3/11=53/88
Hence,
7/8 minus 3/11 equals to 53/88 in fraction.
7/8-3/11 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/8
Fraction B: 3/11
What to be found?
7/8-3/11 = ?
Find what's the difference between 7/8 and 3/11.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (7 x 11), find the product of numerator of Fraction B and denominator of Fraction A (3 x 8), and find the product of both denominators of Fraction A and Fraction B (8 x 11) and rewrite the equation as like the below:
= (7 x 11) - (3 x 8)/(8 x 11)
step 3 Simplify and rewrite the fraction:
= (77 - 24)/88
7/8-3/11 = 53/88
Hence,
7/8 minus 3/11 = 53/88
