9/7 - 1/2 as a fraction

Learn how to find what is 9/7 minus 1/2 in fraction form just in a few minutes. We have covered the easiest method to write 9/7 - 1/2 as a fraction and decimal.

Summary: 9/7 minus 1/2 = 11/14
Since both fractions have unequal denominators, 9/7 minus 1/2 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 9/7 and fraction 1/2 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 7 and 2. 14 is the LCM of 7 and 2. Multiplying the LCM 14 with the numerators and denominators of both fractions (9/7 x 14/14) - (1/2 x 14/14), and simplify further in order to have the common denominator. So the equivalent fraction for 9/7 is 18/14 and for 1/2 is 7/14. By simplifying this fraction subtraction 18/14 - 7/14, it becomes 11/14.

2. Cross multiplication method.

(9/7) - (1/2) using LCM Method:
What is 9/7 minus 1/2 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 9/7
Fraction B: 1/2

What to be found?
(9/7) - (1/2) = ?
Find what's the difference between 9/7 and 1/2.

step 2 Compare the denominators of fractions 9/7 and 1/2 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 9/7 and 1/2 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 9/7 and 1/2:
The LCM of 7 and 2 is 14.

step 4 Write the fractions 9/7 and 1/2 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 9/7 - 1/2
= [(9 x 14)/(7 x 14)] - [(1 x 14)/(2 x 14)]

step 5 Simplify the expression to have common denominator:
= 18/14 - 7/14

step 6 Take the common values out and rewrite the above expression like the below:
= 1/14 x (18/1 - 7/1)
= 1/14 x (18 - 7)

step 7Simplify the above expression further:
= 1/14 x 11
= 11/14
9/7 - 1/2 = 11/14

Hence,
9/7 minus 1/2 as a fraction is 11/14.

9/7 - 1/2 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 9/7
Fraction B: 1/2

What to be found?
(9/7)-(1/2) = ?
Find what's the difference between 9/7 and 1/2.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (9 x 2), find the product of numerator of Fraction B and denominator of Fraction A (1 x 7), and find the product of both denominators of Fraction A and Fraction B (7 x 2) and rewrite the equation as like the below:
= (9 x 2) - (1 x 7)/(7 x 2)

step 3 Simplify and rewrite the fraction:
= (18 - 7)/14
9/7 - 1/2 = 11/14

Hence,
9/7 minus 1/2 in fraction is 11/14
