Learn how to find what is 7/2 minus 6/9 in fraction form just in a few minutes. We have covered the easiest method to write 7/2 - 6/9 as a fraction and decimal.
Summary: 7/2 minus 6/9
Since both the fractions have the unequal denominators, you have to find the equivalent fractions for 7/2 and 6/9 having identical denominators before starting adding the fractions. Find the LCM of denominators, 18 is the LCM of 2 and 9. Multiply the LCM 18 with all the numerators and denominators of both fractions (7/2 x 18/18) - (6/9 x 18/18) and simplify further in order to have the common denominators. By simplifying the fraction subtraction expression becomes 51/18.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 6/9 from 7/2. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 7/2 minus 6/9.
1. LCM method
2. Cross multiplication method.
7/2-6/9 using LCM Method:
What is 7/2 minus 6/9 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/2
Fraction B: 6/9
What to be found?
7/2-6/9 = ?
Find what's the difference between 7/2 and 6/9.
step 2 Compare the denominators of fractions 7/2 and 6/9 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 7/2 and 6/9 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 7/2 and 6/9:
The LCM of 2 and 9 is 18.
step 4 Write the fractions 7/2 and 6/9 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=7/2-6/9
=(7 x 18)/(2 x 18)-(6 x 18)/(9 x 18)
step 5 Simplify the expression to have common denominator:
=63/18-12/18
step 6 Take the common values out and rewrite the above expression like the below:
=1/18 x (63/1-12/1)
=1/18 x (63 - 12)
step 7Simplify the above expression further:
=1/18 x 51
= 51/18
=17/6
7/2-6/9=17/6
Hence,
7/2 minus 6/9 equals to 17/6 in fraction.
7/2-6/9 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/2
Fraction B: 6/9
What to be found?
7/2-6/9 = ?
Find what's the difference between 7/2 and 6/9.
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 (6 x 2), and find the product of both denominators of Fraction A and Fraction B (2 x 9) and rewrite the equation as like the below:
= (7 x 9) - (6 x 2)/(2 x 9)
step 3 Simplify and rewrite the fraction:
= (63 - 12)/18
= 51/18
= 17/6
7/2-6/9 = 17/6
Hence,
7/2 minus 6/9 = 17/6
