1/2+2/8 = 3/4.

1/2 + 2/8 = (?)

1/2 + 2/8 = [(1 x 8) + (2 x 2)]/(2 x 8)

= (8 + 4)/16

= 12/16

= (4 x 3)/(4 x 4)

= 3/4

1/2 + 2/8 = 3/4

1/2 is a fraction as an addend,

2/8 is a fraction as an addend,

3/4 is the sum of 1/2 and 2/8.

1/2 + 2/8 = 3/4

3/4 = 0.75

1/2+2/8 as a decimal is 0.75

0.75 is the sum of 1/2 and 2/8.

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

1. LCM method

2. Cross multiplication method.

**1/2+2/8 using LCM Method:**

What is 1/2 plus 2/8 as a fraction?

step 1 Observe the input parameters and what to be found:__Input:__

Fraction A: 1/2

Fraction B: 2/8__What to be found?__

1/2+2/8 = ?

Find what's the sum of 1/2 and 2/8.

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

The LCM of 2 and 8 is 8.

step 4 Write the fractions 1/2 and 2/8 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.

=1/2+2/8

=(1 x 8)/(2 x 8)+(2 x 8)/(8 x 8)

step 5 Simplify the expression to have common denominator:

=4/8+2/8

step 6 Take the common values out and rewrite the above expression like the below:

=1/8 x (4/1+2/1)

=1/8 x (4 + 2)

step 7Simplify the above expression further:

=1/8 x 6

= *6/8*

=3/4

1/2+2/8=3/4

Hence,

1/2 plus 2/8 equals to **3/4** in fraction.

**1/2+2/8 using Cross Multiplication Method:**

step 1 Observe the input parameters and what to be found:__Input:__

Fraction A: 1/2

Fraction B: 2/8__What to be found?__

1/2+2/8 = ?

Find what's the sum of 1/2 and 2/8.

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 (2 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) + (2 x 2)/(2 x 8)

step 3 Simplify and rewrite the fraction:

= (8 + 4)/16

= 12/16

= 3/4

1/2+2/8 = 3/4

Hence,

1/2 plus 2/8 = **3/4**
