Find the LCM of denominators, 18 is the LCM of 9 and 18. Multiply the LCM 18 with all the numerators and denominators of both fractions (1/9 x 18/18) + (1/18 x 18/18) and simplify further in order to have the common denominators. By simplifying the fraction addition expression becomes 3/18.
The below workout with step by step calculation shows how to find the equivalent fraction between 1/9 and 1/18 by adding two fractions with different, unequal or unlike denominators. The sum in fraction form for 1/9 plus 1/18 can be obtained by using anyone of the two methods below.
1. LCM method
2. Cross multiplication method.
1/9+1/18 using LCM Method:
What is 1/9 plus 1/18 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/9
Fraction B: 1/18
What to be found?
1/9+1/18 = ?
Find what's the sum of 1/9 and 1/18.
step 2 Compare the denominators of fractions 1/9 and 1/18 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 1/9 and 1/18 are not equal, it is said to be unlike fractions addition.
step 3For unlike fractions addition, find the LCM (least common multiple) of both denominators of fractions 1/9 and 1/18:
The LCM of 9 and 18 is 18.
step 4 Write the fractions 1/9 and 1/18 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
=1/9+1/18
=(1 x 18)/(9 x 18)+(1 x 18)/(18 x 18)
step 5 Simplify the expression to have common denominator:
=2/18+1/18
step 6 Take the common values out and rewrite the above expression like the below:
=1/18 x (2/1+1/1)
=1/18 x (2 + 1)
step 7Simplify the above expression further:
=1/18 x 3
= 3/18
=1/6
1/9+1/18=1/6
Hence,
1/9 plus 1/18 equals to 1/6 in fraction.
1/9+1/18 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/9
Fraction B: 1/18
What to be found?
1/9+1/18 = ?
Find what's the sum of 1/9 and 1/18.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (1 x 18), find the product of numerator of Fraction B and denominator of Fraction A (1 x 9), and find the product of both denominators of Fraction A and Fraction B (9 x 18) and rewrite the equation as like the below:
= (1 x 18) + (1 x 9)/(9 x 18)
step 3 Simplify and rewrite the fraction:
= (18 + 9)/162
= 27/162
= 1/6
1/9+1/18 = 1/6
Hence,
1/9 plus 1/18 = 1/6
