Find the LCM of denominators, 18 is the LCM of 2 and 18. Multiply the LCM 18 with all the numerators and denominators of both fractions (1/2 x 18/18) + (5/18 x 18/18) and simplify further in order to have the common denominators. By simplifying the fraction addition expression becomes 14/18.
The below workout with step by step calculation shows how to find the equivalent fraction between 1/2 and 5/18 by adding two fractions with different, unequal or unlike denominators. The sum in fraction form for 1/2 plus 5/18 can be obtained by using anyone of the two methods below.
1. LCM method
2. Cross multiplication method.
1/2+5/18 using LCM Method:
What is 1/2 plus 5/18 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/2
Fraction B: 5/18
What to be found?
1/2+5/18 = ?
Find what's the sum of 1/2 and 5/18.
step 2 Compare the denominators of fractions 1/2 and 5/18 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 1/2 and 5/18 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 1/2 and 5/18:
The LCM of 2 and 18 is 18.
step 4 Write the fractions 1/2 and 5/18 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
=1/2+5/18
=(1 x 18)/(2 x 18)+(5 x 18)/(18 x 18)
step 5 Simplify the expression to have common denominator:
=9/18+5/18
step 6 Take the common values out and rewrite the above expression like the below:
=1/18 x (9/1+5/1)
=1/18 x (9 + 5)
step 7Simplify the above expression further:
=1/18 x 14
= 14/18
=7/9
1/2+5/18=7/9
Hence,
1/2 plus 5/18 equals to 7/9 in fraction.
1/2+5/18 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/2
Fraction B: 5/18
What to be found?
1/2+5/18 = ?
Find what's the sum of 1/2 and 5/18.
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 (5 x 2), and find the product of both denominators of Fraction A and Fraction B (2 x 18) and rewrite the equation as like the below:
= (1 x 18) + (5 x 2)/(2 x 18)
step 3 Simplify and rewrite the fraction:
= (18 + 10)/36
= 28/36
= 7/9
1/2+5/18 = 7/9
Hence,
1/2 plus 5/18 = 7/9
