By simplifying the fraction subtraction expression becomes 41/99.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 4/11 from 7/9. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 7/9 minus 4/11.
1. LCM method
2. Cross multiplication method.
7/9-4/11 using LCM Method:
What is 7/9 minus 4/11 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/9
Fraction B: 4/11
What to be found?
7/9-4/11 = ?
Find what's the difference between 7/9 and 4/11.
step 2 Compare the denominators of fractions 7/9 and 4/11 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 7/9 and 4/11 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 7/9 and 4/11:
The LCM of 9 and 11 is 99.
step 4 Write the fractions 7/9 and 4/11 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=7/9-4/11
=(7 x 99)/(9 x 99)-(4 x 99)/(11 x 99)
step 5 Simplify the expression to have common denominator:
=77/99-36/99
step 6 Take the common values out and rewrite the above expression like the below:
=1/99 x (77/1-36/1)
=1/99 x (77 - 36)
step 7Simplify the above expression further:
=1/99 x 41
=41/99
7/9-4/11=41/99
Hence,
7/9 minus 4/11 equals to 41/99 in fraction.
7/9-4/11 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/9
Fraction B: 4/11
What to be found?
7/9-4/11 = ?
Find what's the difference between 7/9 and 4/11.
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 (4 x 9), and find the product of both denominators of Fraction A and Fraction B (9 x 11) and rewrite the equation as like the below:
= (7 x 11) - (4 x 9)/(9 x 11)
step 3 Simplify and rewrite the fraction:
= (77 - 36)/99
7/9-4/11 = 41/99
Hence,
7/9 minus 4/11 = 41/99
