Find the LCM of denominators, 9 is the LCM of 3 and 9. Multiply the LCM 9 with all the numerators and denominators of both fractions (7/3 x 9/9) - (2/9 x 9/9) and simplify further in order to have the common denominators. By simplifying the fraction subtraction expression becomes 19/9.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 2/9 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 2/9.
1. LCM method
2. Cross multiplication method.
7/3-2/9 using LCM Method:
What is 7/3 minus 2/9 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/3
Fraction B: 2/9
What to be found?
7/3-2/9 = ?
Find what's the difference between 7/3 and 2/9.
step 2 Compare the denominators of fractions 7/3 and 2/9 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 7/3 and 2/9 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 2/9:
The LCM of 3 and 9 is 9.
step 4 Write the fractions 7/3 and 2/9 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=7/3-2/9
=(7 x 9)/(3 x 9)-(2 x 9)/(9 x 9)
step 5 Simplify the expression to have common denominator:
=21/9-2/9
step 6 Take the common values out and rewrite the above expression like the below:
=1/9 x (21/1-2/1)
=1/9 x (21 - 2)
step 7Simplify the above expression further:
=1/9 x 19
=19/9
7/3-2/9=19/9
Hence,
7/3 minus 2/9 equals to 19/9 in fraction.
7/3-2/9 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/3
Fraction B: 2/9
What to be found?
7/3-2/9 = ?
Find what's the difference between 7/3 and 2/9.
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 (2 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) - (2 x 3)/(3 x 9)
step 3 Simplify and rewrite the fraction:
= (63 - 6)/27
= 57/27
= 19/9
7/3-2/9 = 19/9
Hence,
7/3 minus 2/9 = 19/9
