4/1 + 1/2 as a fraction

Learn how to find what is 4/1 plus 1/2 in fraction form just in a few minutes. We have covered the easiest method to write 4/1 + 1/2 as a fraction and decimal.

Summary: 4/1 plus 1/2 = 9/2
Since both fractions have unequal denominators, 4/1 plus 1/2 is an unlike fractions addition. For adding unlike fractions, you have to first find the equivalent fractions for fraction 4/1 and fraction 1/2 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 1 and 2. 2 is the LCM of 1 and 2. Multiplying the LCM 2 with the numerators and denominators of both fractions (4/1 x 2/2) + (1/2 x 2/2), and simplify further in order to have the common denominator. So the equivalent fraction for 4/1 is 8/2 and for 1/2 is 1/2. By simplifying this fraction addition 8/2 + 1/2, it becomes 9/2.

CALCULATION: 4/1 + 1/2 as a fraction
4/1 + 1/2 = (?)
4/1 + 1/2 = [(4 x 2) + (1 x 1)]/(1 x 2)
= (8 + 1)/2
= 9/2
4/1 + 1/2 = 9/2
4/1 plus 1/2 as a fraction is 9/2.

where
4/1 is a improper fraction as an addend,
1/2 is a proper fraction as an addend,
9/2 is the sum of 4/1 and 1/2.

The below workout with step by step calculation shows how to find the equivalent fraction between 4/1 and 1/2 by adding two fractions with different, unequal or unlike denominators. The sum in fraction form for 4/1 plus 1/2 can be obtained by using anyone of the two methods below.
1. LCM method
2. Cross multiplication method.

(4/1) + (1/2) using LCM Method:
What is 4/1 plus 1/2 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 4/1
Fraction B: 1/2

What to be found?
(4/1) + (1/2) = ?
Find what's the sum of 4/1 and 1/2.

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

step 4 Write the fractions 4/1 and 1/2 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 4/1 + 1/2
= [(4 x 2)/(1 x 2)] + [(1 x 2)/(2 x 2)]

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

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

step 7Simplify the above expression further:
= 1/2 x 9
= 9/2
4/1 + 1/2 = 9/2

Hence,
4/1 plus 1/2 as a fraction is 9/2.

4/1 + 1/2 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 4/1
Fraction B: 1/2

What to be found?
(4/1)+(1/2) = ?
Find what's the sum of 4/1 and 1/2.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (4 x 2), find the product of numerator of Fraction B and denominator of Fraction A (1 x 1), and find the product of both denominators of Fraction A and Fraction B (1 x 2) and rewrite the equation as like the below:
= (4 x 2) + (1 x 1)/(1 x 2)

step 3 Simplify and rewrite the fraction:
= (8 + 1)/2
4/1 + 1/2 = 9/2

Hence,
4/1 plus 1/2 in fraction is 9/2
