Learn how to find what is 9/7 minus 3/4 in fraction form just in a few minutes. We have covered the easiest method to write 9/7 - 3/4 as a fraction and decimal.
Summary: 9/7 minus 3/4
Since both the fractions have the unequal denominators, you have to find the equivalent fractions for 9/7 and 3/4 having identical denominators before starting adding the fractions. Find the LCM of denominators, 28 is the LCM of 7 and 4. Multiply the LCM 28 with all the numerators and denominators of both fractions (9/7 x 28/28) - (3/4 x 28/28) and simplify further in order to have the common denominators. By simplifying the fraction subtraction expression becomes 15/28.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 3/4 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 3/4.
1. LCM method
2. Cross multiplication method.
9/7-3/4 using LCM Method:
What is 9/7 minus 3/4 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 9/7
Fraction B: 3/4
What to be found?
9/7-3/4 = ?
Find what's the difference between 9/7 and 3/4.
step 2 Compare the denominators of fractions 9/7 and 3/4 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 9/7 and 3/4 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 3/4:
The LCM of 7 and 4 is 28.
step 4 Write the fractions 9/7 and 3/4 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=9/7-3/4
=(9 x 28)/(7 x 28)-(3 x 28)/(4 x 28)
step 5 Simplify the expression to have common denominator:
=36/28-21/28
step 6 Take the common values out and rewrite the above expression like the below:
=1/28 x (36/1-21/1)
=1/28 x (36 - 21)
step 7Simplify the above expression further:
=1/28 x 15
=15/28
9/7-3/4=15/28
Hence,
9/7 minus 3/4 equals to 15/28 in fraction.
9/7-3/4 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 9/7
Fraction B: 3/4
What to be found?
9/7-3/4 = ?
Find what's the difference between 9/7 and 3/4.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (9 x 4), 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 4) and rewrite the equation as like the below:
= (9 x 4) - (3 x 7)/(7 x 4)
step 3 Simplify and rewrite the fraction:
= (36 - 21)/28
9/7-3/4 = 15/28
Hence,
9/7 minus 3/4 = 15/28
