1/5 + 3/20 as a fraction

Learn how to find what is 1/5 plus 3/20 in fraction form just in a few minutes. We have covered the easiest method to write 1/5 + 3/20 as a fraction and decimal.

Summary: 1/5 plus 3/20 = 7/20
Since both fractions have unequal denominators, 1/5 plus 3/20 is an unlike fractions addition. For adding unlike fractions, you have to first find the equivalent fractions for fraction 1/5 and fraction 3/20 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 5 and 20. 20 is the LCM of 5 and 20. Multiplying the LCM 20 with the numerators and denominators of both fractions (1/5 x 20/20) + (3/20 x 20/20), and simplify further in order to have the common denominator. So the equivalent fraction for 1/5 is 4/20 and for 3/20 is 3/20. By simplifying this fraction addition 4/20 + 3/20, it becomes 7/20.

The below workout with step by step calculation shows how to find the equivalent fraction between 1/5 and 3/20 by adding two fractions with different, unequal or unlike denominators. The sum in fraction form for 1/5 plus 3/20 can be obtained by using anyone of the two methods below.
1. LCM method
2. Cross multiplication method.

(1/5) + (3/20) using LCM Method:
What is 1/5 plus 3/20 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/5
Fraction B: 3/20

What to be found?
(1/5) + (3/20) = ?
Find what's the sum of 1/5 and 3/20.

step 2 Compare the denominators of fractions 1/5 and 3/20 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 1/5 and 3/20 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 1/5 and 3/20:
The LCM of 5 and 20 is 20.

step 4 Write the fractions 1/5 and 3/20 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 1/5 + 3/20
= [(1 x 20)/(5 x 20)] + [(3 x 20)/(20 x 20)]

step 5 Simplify the expression to have common denominator:
= 4/20 + 3/20

step 6 Take the common values out and rewrite the above expression like the below:
= 1/20 x (4/1 + 3/1)
= 1/20 x (4 + 3)

step 7Simplify the above expression further:
= 1/20 x 7
= 7/20
1/5 + 3/20 = 7/20

Hence,
1/5 plus 3/20 as a fraction is 7/20.

1/5 + 3/20 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/5
Fraction B: 3/20

What to be found?
(1/5)+(3/20) = ?
Find what's the sum of 1/5 and 3/20.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (1 x 20), find the product of numerator of Fraction B and denominator of Fraction A (3 x 5), and find the product of both denominators of Fraction A and Fraction B (5 x 20) and rewrite the equation as like the below:
= (1 x 20) + (3 x 5)/(5 x 20)

step 3 Simplify and rewrite the fraction:
= (20 + 15)/100
= 35/100
= 7/20
