1/7 + 2/81 as a fraction

Learn how to find what is 1/7 plus 2/81 in fraction form just in a few minutes. We have covered the easiest method to write 1/7 + 2/81 as a fraction and decimal.

Summary: 1/7 plus 2/81 = 95/567
Since both fractions have unequal denominators, 1/7 plus 2/81 is an unlike fractions addition. For adding unlike fractions, you have to first find the equivalent fractions for fraction 1/7 and fraction 2/81 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 7 and 81. 567 is the LCM of 7 and 81. Multiplying the LCM 567 with the numerators and denominators of both fractions (1/7 x 567/567) + (2/81 x 567/567), and simplify further in order to have the common denominator. So the equivalent fraction for 1/7 is 81/567 and for 2/81 is 14/567. By simplifying this fraction addition 81/567 + 14/567, it becomes 95/567.

2. Cross multiplication method.

(1/7) + (2/81) using LCM Method:
What is 1/7 plus 2/81 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/7
Fraction B: 2/81

What to be found?
(1/7) + (2/81) = ?
Find what's the sum of 1/7 and 2/81.

step 2 Compare the denominators of fractions 1/7 and 2/81 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 1/7 and 2/81 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 1/7 and 2/81:
The LCM of 7 and 81 is 567.

step 4 Write the fractions 1/7 and 2/81 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 1/7 + 2/81
= [(1 x 567)/(7 x 567)] + [(2 x 567)/(81 x 567)]

step 5 Simplify the expression to have common denominator:
= 81/567 + 14/567

step 6 Take the common values out and rewrite the above expression like the below:
= 1/567 x (81/1 + 14/1)
= 1/567 x (81 + 14)

step 7Simplify the above expression further:
= 1/567 x 95
= 95/567
1/7 + 2/81 = 95/567

Hence,
1/7 plus 2/81 as a fraction is 95/567.
