Learn how to find what is 3/6 minus 4/9 in fraction form just in a few minutes. We have covered the easiest method to write 3/6 - 4/9 as a fraction and decimal.
Summary: 3/6 minus 4/9
Since both the fractions have the unequal denominators, you have to find the equivalent fractions for 3/6 and 4/9 having identical denominators before starting adding the fractions. Find the LCM of denominators, 18 is the LCM of 6 and 9. Multiply the LCM 18 with all the numerators and denominators of both fractions (3/6 x 18/18) - (4/9 x 18/18) and simplify further in order to have the common denominators. By simplifying the fraction subtraction expression becomes 1/18.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 4/9 from 3/6. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 3/6 minus 4/9.
1. LCM method
2. Cross multiplication method.
3/6-4/9 using LCM Method:
What is 3/6 minus 4/9 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 3/6
Fraction B: 4/9
What to be found?
3/6-4/9 = ?
Find what's the difference between 3/6 and 4/9.
step 2 Compare the denominators of fractions 3/6 and 4/9 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 3/6 and 4/9 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 3/6 and 4/9:
The LCM of 6 and 9 is 18.
step 4 Write the fractions 3/6 and 4/9 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=3/6-4/9
=(3 x 18)/(6 x 18)-(4 x 18)/(9 x 18)
step 5 Simplify the expression to have common denominator:
=9/18-8/18
step 6 Take the common values out and rewrite the above expression like the below:
=1/18 x (9/1-8/1)
=1/18 x (9 - 8)
step 7Simplify the above expression further:
=1/18 x 1
=1/18
3/6-4/9=1/18
Hence,
3/6 minus 4/9 equals to 1/18 in fraction.
3/6-4/9 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 3/6
Fraction B: 4/9
What to be found?
3/6-4/9 = ?
Find what's the difference between 3/6 and 4/9.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (3 x 9), find the product of numerator of Fraction B and denominator of Fraction A (4 x 6), and find the product of both denominators of Fraction A and Fraction B (6 x 9) and rewrite the equation as like the below:
= (3 x 9) - (4 x 6)/(6 x 9)
step 3 Simplify and rewrite the fraction:
= (27 - 24)/54
= 3/54
= 1/18
3/6-4/9 = 1/18
Hence,
3/6 minus 4/9 = 1/18
