What is 1/2 plus 1/8 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/2
Fraction B: 1/8
What to be found?
1/2+1/8 = ?
Find what's the sum of 1/2 and 1/8.
step 2 Compare the denominators of fractions 1/2 and 1/8 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 1/2 and 1/8 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 1/2 and 1/8:
The LCM of 2 and 8 is 8.
step 4 Write the fractions 1/2 and 1/8 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
=1/2+1/8
=(1 x 8)/(2 x 8)+(1 x 8)/(8 x 8)
step 5 Simplify the expression to have common denominator:
=4/8+1/8
step 6 Take the common values out and rewrite the above expression like the below:
=1/8 x (4/1+1/1)
=1/8 x (4 + 1)
step 7Simplify the above expression further:
=1/8 x 5
=5/8
1/2+1/8=5/8
Hence,
1/2 plus 1/8 equals to 5/8 in fraction.

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/2
Fraction B: 1/8
What to be found?
1/2+1/8 = ?
Find what's the sum of 1/2 and 1/8.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (1 x 8), find the product of numerator of Fraction B and denominator of Fraction A (1 x 2), and find the product of both denominators of Fraction A and Fraction B (2 x 8) and rewrite the equation as like the below:
= (1 x 8) + (1 x 2)/(2 x 8)
step 3 Simplify and rewrite the fraction:
= (8 + 2)/16
= 10/16
= 5/8
1/2+1/8 = 5/8
Hence,
1/2 plus 1/8 = 5/8
