By simplifying the fraction subtraction expression becomes 8/9.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 7/9 from 5/3. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 5/3 minus 7/9.
1. LCM method
2. Cross multiplication method.
5/3-7/9 using LCM Method:
What is 5/3 minus 7/9 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 5/3
Fraction B: 7/9
What to be found?
5/3-7/9 = ?
Find what's the difference between 5/3 and 7/9.
step 2 Compare the denominators of fractions 5/3 and 7/9 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 5/3 and 7/9 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 5/3 and 7/9:
The LCM of 3 and 9 is 9.
step 4 Write the fractions 5/3 and 7/9 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=5/3-7/9
=(5 x 9)/(3 x 9)-(7 x 9)/(9 x 9)
step 5 Simplify the expression to have common denominator:
=15/9-7/9
step 6 Take the common values out and rewrite the above expression like the below:
=1/9 x (15/1-7/1)
=1/9 x (15 - 7)
step 7Simplify the above expression further:
=1/9 x 8
=8/9
5/3-7/9=8/9
Hence,
5/3 minus 7/9 equals to 8/9 in fraction.
5/3-7/9 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 5/3
Fraction B: 7/9
What to be found?
5/3-7/9 = ?
Find what's the difference between 5/3 and 7/9.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (5 x 9), find the product of numerator of Fraction B and denominator of Fraction A (7 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:
= (5 x 9) - (7 x 3)/(3 x 9)
step 3 Simplify and rewrite the fraction:
= (45 - 21)/27
= 24/27
= 8/9
5/3-7/9 = 8/9
Hence,
5/3 minus 7/9 = 8/9
