Learn how to find what is 11/3 plus 2/7 in fraction form just in a few minutes. We have covered the easiest method to write 11/3 + 2/7 as a fraction and decimal.

Summary: 11/3 plus 2/7 = 83/21
Since both fractions have unequal denominators, 11/3 plus 2/7 is an unlike fractions addition. For adding unlike fractions, you have to first find the equivalent fractions for fraction 11/3 and fraction 2/7 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 3 and 7. 21 is the LCM of 3 and 7. Multiplying the LCM 21 with the numerators and denominators of both fractions (11/3 x 21/21) + (2/7 x 21/21), and simplify further in order to have the common denominator. So the equivalent fraction for 11/3 is 77/21 and for 2/7 is 6/21. By simplifying this fraction addition 77/21 + 6/21, it becomes 83/21.

2. Cross multiplication method.

(11/3) + (2/7) using LCM Method:
What is 11/3 plus 2/7 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 11/3
Fraction B: 2/7

What to be found?
(11/3) + (2/7) = ?
Find what's the sum of 11/3 and 2/7.

step 2 Compare the denominators of fractions 11/3 and 2/7 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 11/3 and 2/7 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 11/3 and 2/7:
The LCM of 3 and 7 is 21.

step 4 Write the fractions 11/3 and 2/7 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 11/3 + 2/7
= [(11 x 21)/(3 x 21)] + [(2 x 21)/(7 x 21)]

step 5 Simplify the expression to have common denominator:
= 77/21 + 6/21

step 6 Take the common values out and rewrite the above expression like the below:
= 1/21 x (77/1 + 6/1)
= 1/21 x (77 + 6)

step 7Simplify the above expression further:
= 1/21 x 83
= 83/21
11/3 + 2/7 = 83/21

Hence,
11/3 plus 2/7 as a fraction is 83/21.
