Learn how to find what is 7/9 plus 5/12 in fraction form just in a few minutes. We have covered the easiest method to write 7/9 + 5/12 as a fraction and decimal.
Summary: 7/9 plus 5/12 = 43/36
Since both fractions have unequal denominators, 7/9 plus 5/12 is an unlike fractions addition. For adding unlike fractions, you have to first find the equivalent fractions for fraction 7/9 and fraction 5/12 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 9 and 12. 36 is the LCM of 9 and 12. Multiplying the LCM 36 with the numerators and denominators of both fractions (7/9 x 36/36) + (5/12 x 36/36), and simplify further in order to have the common denominator. So the equivalent fraction for 7/9 is 28/36 and for 5/12 is 15/36. By simplifying this fraction addition 28/36 + 15/36, it becomes 43/36.
The below workout with step by step calculation shows how to find the equivalent fraction between 7/9 and 5/12 by adding two fractions with different, unequal or unlike denominators. The sum in fraction form for 7/9 plus 5/12 can be obtained by using anyone of the two methods below.
1. LCM method
2. Cross multiplication method.
(7/9) + (5/12) using LCM Method:
What is 7/9 plus 5/12 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/9
Fraction B: 5/12
What to be found?
(7/9) + (5/12) = ?
Find what's the sum of 7/9 and 5/12.
step 2 Compare the denominators of fractions 7/9 and 5/12 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 7/9 and 5/12 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 7/9 and 5/12:
The LCM of 9 and 12 is 36.
step 4 Write the fractions 7/9 and 5/12 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 7/9 + 5/12
= [(7 x 36)/(9 x 36)] + [(5 x 36)/(12 x 36)]
step 5 Simplify the expression to have common denominator:
= 28/36 + 15/36
step 6 Take the common values out and rewrite the above expression like the below:
= 1/36 x (28/1 + 15/1)
= 1/36 x (28 + 15)
step 7Simplify the above expression further:
= 1/36 x 43
= 43/36
7/9 + 5/12 = 43/36
Hence,
7/9 plus 5/12 as a fraction is 43/36.
7/9 + 5/12 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/9
Fraction B: 5/12
What to be found?
(7/9)+(5/12) = ?
Find what's the sum of 7/9 and 5/12.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (7 x 12), 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 12) and rewrite the equation as like the below:
= (7 x 12) + (5 x 9)/(9 x 12)
step 3 Simplify and rewrite the fraction:
= (84 + 45)/108
= 129/108
= 43/36
7/9 + 5/12 = 43/36
Hence,
7/9 plus 5/12 in fraction is 43/36
