By simplifying the fraction subtraction expression becomes 10/9.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 11/9 from 7/3. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 7/3 minus 11/9.
1. LCM method
2. Cross multiplication method.
7/3-11/9 using LCM Method:
What is 7/3 minus 11/9 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/3
Fraction B: 11/9
What to be found?
7/3-11/9 = ?
Find what's the difference between 7/3 and 11/9.
step 2 Compare the denominators of fractions 7/3 and 11/9 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 7/3 and 11/9 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 7/3 and 11/9:
The LCM of 3 and 9 is 9.
step 4 Write the fractions 7/3 and 11/9 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=7/3-11/9
=(7 x 9)/(3 x 9)-(11 x 9)/(9 x 9)
step 5 Simplify the expression to have common denominator:
=21/9-11/9
step 6 Take the common values out and rewrite the above expression like the below:
=1/9 x (21/1-11/1)
=1/9 x (21 - 11)
step 7Simplify the above expression further:
=1/9 x 10
=10/9
7/3-11/9=10/9
Hence,
7/3 minus 11/9 equals to 10/9 in fraction.
7/3-11/9 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/3
Fraction B: 11/9
What to be found?
7/3-11/9 = ?
Find what's the difference between 7/3 and 11/9.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (7 x 9), find the product of numerator of Fraction B and denominator of Fraction A (11 x 3), and find the product of both denominators of Fraction A and Fraction B (3 x 9) and rewrite the equation as like the below:
= (7 x 9) - (11 x 3)/(3 x 9)
step 3 Simplify and rewrite the fraction:
= (63 - 33)/27
= 30/27
= 10/9
7/3-11/9 = 10/9
Hence,
7/3 minus 11/9 = 10/9
