Learn how to find what is 9/7 minus 3/2 in fraction form just in a few minutes. We have covered the easiest method to write 9/7 - 3/2 as a fraction and decimal.
Summary: 9/7 minus 3/2
Since both the fractions have the unequal denominators, you have to find the equivalent fractions for 9/7 and 3/2 having identical denominators before starting adding the fractions. Find the LCM of denominators, 14 is the LCM of 7 and 2. Multiply the LCM 14 with all the numerators and denominators of both fractions (9/7 x 14/14) - (3/2 x 14/14) and simplify further in order to have the common denominators. By simplifying the fraction subtraction expression becomes -3/14.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 3/2 from 9/7. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 9/7 minus 3/2.
1. LCM method
2. Cross multiplication method.
9/7-3/2 using LCM Method:
What is 9/7 minus 3/2 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 9/7
Fraction B: 3/2
What to be found?
9/7-3/2 = ?
Find what's the difference between 9/7 and 3/2.
step 2 Compare the denominators of fractions 9/7 and 3/2 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 9/7 and 3/2 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 3/2:
The LCM of 7 and 2 is 14.
step 4 Write the fractions 9/7 and 3/2 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=9/7-3/2
=(9 x 14)/(7 x 14)-(3 x 14)/(2 x 14)
step 5 Simplify the expression to have common denominator:
=18/14-21/14
step 6 Take the common values out and rewrite the above expression like the below:
=1/14 x (18/1-21/1)
=1/14 x (18 - 21)
step 7Simplify the above expression further:
=1/14 x -3
=-3/14
9/7-3/2=-3/14
Hence,
9/7 minus 3/2 equals to -3/14 in fraction.
9/7-3/2 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 9/7
Fraction B: 3/2
What to be found?
9/7-3/2 = ?
Find what's the difference between 9/7 and 3/2.
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 (3 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) - (3 x 7)/(7 x 2)
step 3 Simplify and rewrite the fraction:
= (18 - 21)/14
9/7-3/2 = -3/14
Hence,
9/7 minus 3/2 = -3/14
