Multiply the LCM 28 with all the numerators and denominators of both fractions (3/4 x 28/28) - (9/14 x 28/28) and simplify further in order to have the common denominators. By simplifying the fraction subtraction expression becomes 3/28.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 9/14 from 3/4. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 3/4 minus 9/14.
1. LCM method
2. Cross multiplication method.
3/4-9/14 using LCM Method:
What is 3/4 minus 9/14 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 3/4
Fraction B: 9/14
What to be found?
3/4-9/14 = ?
Find what's the difference between 3/4 and 9/14.
step 2 Compare the denominators of fractions 3/4 and 9/14 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 3/4 and 9/14 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 3/4 and 9/14:
The LCM of 4 and 14 is 28.
step 4 Write the fractions 3/4 and 9/14 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=3/4-9/14
=(3 x 28)/(4 x 28)-(9 x 28)/(14 x 28)
step 5 Simplify the expression to have common denominator:
=21/28-18/28
step 6 Take the common values out and rewrite the above expression like the below:
=1/28 x (21/1-18/1)
=1/28 x (21 - 18)
step 7Simplify the above expression further:
=1/28 x 3
=3/28
3/4-9/14=3/28
Hence,
3/4 minus 9/14 equals to 3/28 in fraction.
3/4-9/14 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 3/4
Fraction B: 9/14
What to be found?
3/4-9/14 = ?
Find what's the difference between 3/4 and 9/14.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (3 x 14), find the product of numerator of Fraction B and denominator of Fraction A (9 x 4), and find the product of both denominators of Fraction A and Fraction B (4 x 14) and rewrite the equation as like the below:
= (3 x 14) - (9 x 4)/(4 x 14)
step 3 Simplify and rewrite the fraction:
= (42 - 36)/56
= 6/56
= 3/28
3/4-9/14 = 3/28
Hence,
3/4 minus 9/14 = 3/28
