Learn how to find what is 3/4 plus 1/2 in fraction form just in a few minutes. We have covered the easiest method to write 3/4 + 1/2 as a fraction and decimal.
Summary: 3/4 plus 1/2
Since both the fractions have the unequal denominators, you have to find the equivalent fractions for 3/4 and 1/2 having identical denominators before starting adding the fractions. Find the LCM of denominators, 4 is the LCM of 4 and 2. Multiply the LCM 4 with all the numerators and denominators of both fractions (3/4 x 4/4) + (1/2 x 4/4) and simplify further in order to have the common denominators. By simplifying the fraction addition expression becomes 5/4.
The below workout with step by step calculation shows how to find the equivalent fraction between 3/4 and 1/2 by adding two fractions with different, unequal or unlike denominators. The sum in fraction form for 3/4 plus 1/2 can be obtained by using anyone of the two methods below.
1. LCM method
2. Cross multiplication method.
3/4+1/2 using LCM Method:
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.
3/4+1/2 using 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
