Learn how to find what is 9/3 minus 7/4 in fraction form just in a few minutes. We have covered the easiest method to write 9/3 - 7/4 as a fraction and decimal.
Summary: 9/3 minus 7/4
Since both the fractions have the unequal denominators, you have to find the equivalent fractions for 9/3 and 7/4 having identical denominators before starting adding the fractions. Find the LCM of denominators, 12 is the LCM of 3 and 4. Multiply the LCM 12 with all the numerators and denominators of both fractions (9/3 x 12/12) - (7/4 x 12/12) and simplify further in order to have the common denominators. By simplifying the fraction subtraction expression becomes 15/12.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 7/4 from 9/3. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 9/3 minus 7/4.
1. LCM method
2. Cross multiplication method.
9/3-7/4 using LCM Method:
What is 9/3 minus 7/4 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 9/3
Fraction B: 7/4
What to be found?
9/3-7/4 = ?
Find what's the difference between 9/3 and 7/4.
step 2 Compare the denominators of fractions 9/3 and 7/4 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 9/3 and 7/4 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 9/3 and 7/4:
The LCM of 3 and 4 is 12.
step 4 Write the fractions 9/3 and 7/4 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=9/3-7/4
=(9 x 12)/(3 x 12)-(7 x 12)/(4 x 12)
step 5 Simplify the expression to have common denominator:
=36/12-21/12
step 6 Take the common values out and rewrite the above expression like the below:
=1/12 x (36/1-21/1)
=1/12 x (36 - 21)
step 7Simplify the above expression further:
=1/12 x 15
= 15/12
=5/4
9/3-7/4=5/4
Hence,
9/3 minus 7/4 equals to 5/4 in fraction.
9/3-7/4 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 9/3
Fraction B: 7/4
What to be found?
9/3-7/4 = ?
Find what's the difference between 9/3 and 7/4.
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 (7 x 3), and find the product of both denominators of Fraction A and Fraction B (3 x 4) and rewrite the equation as like the below:
= (9 x 4) - (7 x 3)/(3 x 4)
step 3 Simplify and rewrite the fraction:
= (36 - 21)/12
= 15/12
= 5/4
9/3-7/4 = 5/4
Hence,
9/3 minus 7/4 = 5/4
