Learn how to find what is 2/8 plus 1/42 in fraction form just in a few minutes. We have covered the easiest method to write 2/8 + 1/42 as a fraction and decimal.

Summary: 2/8 plus 1/42 = 23/84
Since both fractions have unequal denominators, 2/8 plus 1/42 is an unlike fractions addition. For adding unlike fractions, you have to first find the equivalent fractions for fraction 2/8 and fraction 1/42 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 8 and 42. 168 is the LCM of 8 and 42. Multiplying the LCM 168 with the numerators and denominators of both fractions (2/8 x 168/168) + (1/42 x 168/168), and simplify further in order to have the common denominator. So the equivalent fraction for 2/8 is 42/168 and for 1/42 is 4/168. By simplifying this fraction addition 42/168 + 4/168, it becomes 46/168.

The below workout with step by step calculation shows how to find the equivalent fraction between 2/8 and 1/42 by adding two fractions with different, unequal or unlike denominators. The sum in fraction form for 2/8 plus 1/42 can be obtained by using anyone of the two methods below.
1. LCM method
2. Cross multiplication method.

(2/8) + (1/42) using LCM Method:
What is 2/8 plus 1/42 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/8
Fraction B: 1/42

What to be found?
(2/8) + (1/42) = ?
Find what's the sum of 2/8 and 1/42.

step 2 Compare the denominators of fractions 2/8 and 1/42 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 2/8 and 1/42 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 2/8 and 1/42:
The LCM of 8 and 42 is 168.

step 4 Write the fractions 2/8 and 1/42 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 2/8 + 1/42
= [(2 x 168)/(8 x 168)] + [(1 x 168)/(42 x 168)]

step 5 Simplify the expression to have common denominator:
= 42/168 + 4/168

step 6 Take the common values out and rewrite the above expression like the below:
= 1/168 x (42/1 + 4/1)
= 1/168 x (42 + 4)

step 7Simplify the above expression further:
= 1/168 x 46
= 46/168
= 23/84
2/8 + 1/42 = 23/84

Hence,
2/8 plus 1/42 as a fraction is 23/84.
