What is 1/4 plus 1/8 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/4
Fraction B: 1/8

What to be found?
1/4+1/8 = ?
Find what's the sum of 1/4 and 1/8.

step 2 Compare the denominators of fractions 1/4 and 1/8 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 1/4 and 1/8 are not equal, it is said to be unlike fractions addition.

The LCM of 4 and 8 is 8.

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

step 5 Simplify the expression to have common denominator:
=2/8+1/8

step 6 Take the common values out and rewrite the above expression like the below:
=1/8 x (2/1+1/1)
=1/8 x (2 + 1)

step 7Simplify the above expression further:
=1/8 x 3
=3/8
1/4+1/8=3/8

Hence,
1/4 plus 1/8 equals to 3/8 in fraction.

Input:
Fraction A: 1/4
Fraction B: 1/8

What to be found?
1/4+1/8 = ?
Find what's the sum of 1/4 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 4), and find the product of both denominators of Fraction A and Fraction B (4 x 8) and rewrite the equation as like the below:
= (1 x 8) + (1 x 4)/(4 x 8)

step 3 Simplify and rewrite the fraction:
= (8 + 4)/32
= 12/32
= 3/8
1/4+1/8 = 3/8
Hence,
1/4 plus 1/8 = 3/8
