2/4 - 1/18 as a fraction

Learn how to find what is 2/4 minus 1/18 in fraction form just in a few minutes. We have covered the easiest method to write 2/4 - 1/18 as a fraction and decimal.

Summary: 2/4 minus 1/18 = 4/9
Since both fractions have unequal denominators, 2/4 minus 1/18 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 2/4 and fraction 1/18 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 4 and 18. 36 is the LCM of 4 and 18. Multiplying the LCM 36 with the numerators and denominators of both fractions (2/4 x 36/36) - (1/18 x 36/36), and simplify further in order to have the common denominator. So the equivalent fraction for 2/4 is 18/36 and for 1/18 is 2/36. By simplifying this fraction subtraction 18/36 - 2/36, it becomes 16/36.

2. Cross multiplication method.

(2/4) - (1/18) using LCM Method:
What is 2/4 minus 1/18 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/4
Fraction B: 1/18

What to be found?
(2/4) - (1/18) = ?
Find what's the difference between 2/4 and 1/18.

step 2 Compare the denominators of fractions 2/4 and 1/18 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 2/4 and 1/18 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 2/4 and 1/18:
The LCM of 4 and 18 is 36.

step 4 Write the fractions 2/4 and 1/18 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 2/4 - 1/18
= [(2 x 36)/(4 x 36)] - [(1 x 36)/(18 x 36)]

step 5 Simplify the expression to have common denominator:
= 18/36 - 2/36

step 6 Take the common values out and rewrite the above expression like the below:
= 1/36 x (18/1 - 2/1)
= 1/36 x (18 - 2)

step 7Simplify the above expression further:
= 1/36 x 16
= 16/36
= 4/9
2/4 - 1/18 = 4/9

Hence,
2/4 minus 1/18 as a fraction is 4/9.

2/4 - 1/18 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/4
Fraction B: 1/18

What to be found?
(2/4)-(1/18) = ?
Find what's the difference between 2/4 and 1/18.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (2 x 18), find the product of numerator of Fraction B and denominator of Fraction A (1 x 4), and find the product of both denominators of Fraction A and Fraction B (4 x 18) and rewrite the equation as like the below:
= (2 x 18) - (1 x 4)/(4 x 18)

step 3 Simplify and rewrite the fraction:
= (36 - 4)/72
= 32/72
= 4/9
