Learn how to find what is 4/9 minus 5/6 in fraction form just in a few minutes. We have covered the easiest method to write 4/9 - 5/6 as a fraction and decimal.
Summary: 4/9 minus 5/6
Since both the fractions have the unequal denominators, you have to find the equivalent fractions for 4/9 and 5/6 having identical denominators before starting adding the fractions. Find the LCM of denominators, 18 is the LCM of 9 and 6. Multiply the LCM 18 with all the numerators and denominators of both fractions (4/9 x 18/18) - (5/6 x 18/18) and simplify further in order to have the common denominators. By simplifying the fraction subtraction expression becomes -7/18.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 5/6 from 4/9. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 4/9 minus 5/6.
1. LCM method
2. Cross multiplication method.
4/9-5/6 using LCM Method:
What is 4/9 minus 5/6 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 4/9
Fraction B: 5/6
What to be found?
4/9-5/6 = ?
Find what's the difference between 4/9 and 5/6.
step 2 Compare the denominators of fractions 4/9 and 5/6 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 4/9 and 5/6 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 5/6:
The LCM of 9 and 6 is 18.
step 4 Write the fractions 4/9 and 5/6 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=4/9-5/6
=(4 x 18)/(9 x 18)-(5 x 18)/(6 x 18)
step 5 Simplify the expression to have common denominator:
=8/18-15/18
step 6 Take the common values out and rewrite the above expression like the below:
=1/18 x (8/1-15/1)
=1/18 x (8 - 15)
step 7Simplify the above expression further:
=1/18 x -7
=-7/18
4/9-5/6=-7/18
Hence,
4/9 minus 5/6 equals to -7/18 in fraction.
4/9-5/6 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 4/9
Fraction B: 5/6
What to be found?
4/9-5/6 = ?
Find what's the difference between 4/9 and 5/6.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (4 x 6), find the product of numerator of Fraction B and denominator of Fraction A (5 x 9), and find the product of both denominators of Fraction A and Fraction B (9 x 6) and rewrite the equation as like the below:
= (4 x 6) - (5 x 9)/(9 x 6)
step 3 Simplify and rewrite the fraction:
= (24 - 45)/54
= -21/54
= -7/18
4/9-5/6 = -7/18
Hence,
4/9 minus 5/6 = -7/18
