Learn how to find what is 7/5 plus 9/20 in fraction form just in a few minutes. We have covered the easiest method to write 7/5 + 9/20 as a fraction and decimal.
Summary: 7/5 plus 9/20 = 37/20
Since both fractions have unequal denominators, 7/5 plus 9/20 is an unlike fractions addition. For adding unlike fractions, you have to first find the equivalent fractions for fraction 7/5 and fraction 9/20 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 (7/5 x 20/20) + (9/20 x 20/20), and simplify further in order to have the common denominator. So the equivalent fraction for 7/5 is 28/20 and for 9/20 is 9/20. By simplifying this fraction addition 28/20 + 9/20, it becomes 37/20.
The below workout with step by step calculation shows how to find the equivalent fraction between 7/5 and 9/20 by adding two fractions with different, unequal or unlike denominators. The sum in fraction form for 7/5 plus 9/20 can be obtained by using anyone of the two methods below.
1. LCM method
2. Cross multiplication method.
(7/5) + (9/20) using LCM Method:
What is 7/5 plus 9/20 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/5
Fraction B: 9/20
What to be found?
(7/5) + (9/20) = ?
Find what's the sum of 7/5 and 9/20.
step 2 Compare the denominators of fractions 7/5 and 9/20 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 7/5 and 9/20 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 7/5 and 9/20:
The LCM of 5 and 20 is 20.
step 4 Write the fractions 7/5 and 9/20 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 7/5 + 9/20
= [(7 x 20)/(5 x 20)] + [(9 x 20)/(20 x 20)]
step 5 Simplify the expression to have common denominator:
= 28/20 + 9/20
step 6 Take the common values out and rewrite the above expression like the below:
= 1/20 x (28/1 + 9/1)
= 1/20 x (28 + 9)
step 7Simplify the above expression further:
= 1/20 x 37
= 37/20
7/5 + 9/20 = 37/20
Hence,
7/5 plus 9/20 as a fraction is 37/20.
7/5 + 9/20 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/5
Fraction B: 9/20
What to be found?
(7/5)+(9/20) = ?
Find what's the sum of 7/5 and 9/20.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (7 x 20), find the product of numerator of Fraction B and denominator of Fraction A (9 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:
= (7 x 20) + (9 x 5)/(5 x 20)
step 3 Simplify and rewrite the fraction:
= (140 + 45)/100
= 185/100
= 37/20
7/5 + 9/20 = 37/20
Hence,
7/5 plus 9/20 in fraction is 37/20
