4/9 - 3/4 as a fraction

Learn how to find what is 4/9 minus 3/4 in fraction form just in a few minutes. We have covered the easiest method to write 4/9 - 3/4 as a fraction and decimal.

Summary: 4/9 minus 3/4 = -11/36
Since both fractions have unequal denominators, 4/9 minus 3/4 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 4/9 and fraction 3/4 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 9 and 4. 36 is the LCM of 9 and 4. Multiplying the LCM 36 with the numerators and denominators of both fractions (4/9 x 36/36) - (3/4 x 36/36), and simplify further in order to have the common denominator. So the equivalent fraction for 4/9 is 16/36 and for 3/4 is 27/36. By simplifying this fraction subtraction 16/36 - 27/36, it becomes -11/36.

2. Cross multiplication method.

(4/9) - (3/4) using LCM Method:
What is 4/9 minus 3/4 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 4/9
Fraction B: 3/4

What to be found?
(4/9) - (3/4) = ?
Find what's the difference between 4/9 and 3/4.

step 2 Compare the denominators of fractions 4/9 and 3/4 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 4/9 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 4/9 and 3/4:
The LCM of 9 and 4 is 36.

step 4 Write the fractions 4/9 and 3/4 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 4/9 - 3/4
= [(4 x 36)/(9 x 36)] - [(3 x 36)/(4 x 36)]

step 5 Simplify the expression to have common denominator:
= 16/36 - 27/36

step 6 Take the common values out and rewrite the above expression like the below:
= 1/36 x (16/1 - 27/1)
= 1/36 x (16 - 27)

step 7Simplify the above expression further:
= 1/36 x -11
= -11/36
4/9 - 3/4 = -11/36

Hence,
4/9 minus 3/4 as a fraction is -11/36.
