What is 3/4 plus 1/2 as a fraction?

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

Fraction A: 3/4

Fraction B: 1/2__What to be found?__

3/4+1/2 = ?

Find what's the sum of 3/4 and 1/2.

step 2 Compare the denominators of fractions 3/4 and 1/2 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 3/4 and 1/2 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 3/4 and 1/2:

The LCM of 4 and 2 is 4.

step 4 Write the fractions 3/4 and 1/2 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.

=3/4+1/2

=(3 x 4)/(4 x 4)+(1 x 4)/(2 x 4)

step 5 Simplify the expression to have common denominator:

=3/4+2/4

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

=1/4 x (3/1+2/1)

=1/4 x (3 + 2)

step 7Simplify the above expression further:

=1/4 x 5

=5/4

3/4+1/2=5/4

Hence,

3/4 plus 1/2 equals to **5/4** in fraction.

__Problem and Workout - Cross Multiplication Method__

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

Fraction A: 3/4

Fraction B: 1/2__What to be found?__

3/4+1/2 = ?

Find what's the sum of 3/4 and 1/2.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (3 x 2), 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 2) and rewrite the equation as like the below:

= (3 x 2) + (1 x 4)/(4 x 2)

step 3 Simplify and rewrite the fraction:

= (6 + 4)/8

= 10/8

= 5/4

3/4+1/2 = 5/4

Hence,

3/4 plus 1/2 = **5/4**
