3/4 + 5/12 as a fraction

Learn how to find what is 3/4 plus 5/12 in fraction form just in a few minutes. We have covered the easiest method to write 3/4 + 5/12 as a fraction and decimal.

Summary: 3/4 plus 5/12 = 7/6
Since both fractions have unequal denominators, 3/4 plus 5/12 is an unlike fractions addition. For adding unlike fractions, you have to first find the equivalent fractions for fraction 3/4 and fraction 5/12 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 4 and 12. 12 is the LCM of 4 and 12. Multiplying the LCM 12 with the numerators and denominators of both fractions (3/4 x 12/12) + (5/12 x 12/12), and simplify further in order to have the common denominator. So the equivalent fraction for 3/4 is 9/12 and for 5/12 is 5/12. By simplifying this fraction addition 9/12 + 5/12, it becomes 14/12.

2. Cross multiplication method.

(3/4) + (5/12) using LCM Method:
What is 3/4 plus 5/12 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 3/4
Fraction B: 5/12

What to be found?
(3/4) + (5/12) = ?
Find what's the sum of 3/4 and 5/12.

step 2 Compare the denominators of fractions 3/4 and 5/12 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 3/4 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 3/4 and 5/12:
The LCM of 4 and 12 is 12.

step 4 Write the fractions 3/4 and 5/12 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 3/4 + 5/12
= [(3 x 12)/(4 x 12)] + [(5 x 12)/(12 x 12)]

step 5 Simplify the expression to have common denominator:
= 9/12 + 5/12

step 6 Take the common values out and rewrite the above expression like the below:
= 1/12 x (9/1 + 5/1)
= 1/12 x (9 + 5)

step 7Simplify the above expression further:
= 1/12 x 14
= 14/12
= 7/6
3/4 + 5/12 = 7/6

Hence,
3/4 plus 5/12 as a fraction is 7/6.
