Learn how to find what is 13/3 plus 2/7 in fraction form just in a few minutes. We have covered the easiest method to write 13/3 + 2/7 as a fraction and decimal.
Summary: 13/3 plus 2/7 = 97/21
Since both fractions have unequal denominators, 13/3 plus 2/7 is an unlike fractions addition. For adding unlike fractions, you have to first find the equivalent fractions for fraction 13/3 and fraction 2/7 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 3 and 7. 21 is the LCM of 3 and 7. Multiplying the LCM 21 with the numerators and denominators of both fractions (13/3 x 21/21) + (2/7 x 21/21), and simplify further in order to have the common denominator. So the equivalent fraction for 13/3 is 91/21 and for 2/7 is 6/21. By simplifying this fraction addition 91/21 + 6/21, it becomes 97/21.
The below workout with step by step calculation shows how to find the equivalent fraction between 13/3 and 2/7 by adding two fractions with different, unequal or unlike denominators. The sum in fraction form for 13/3 plus 2/7 can be obtained by using anyone of the two methods below.
1. LCM method
2. Cross multiplication method.
(13/3) + (2/7) using LCM Method:
What is 13/3 plus 2/7 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 13/3
Fraction B: 2/7
What to be found?
(13/3) + (2/7) = ?
Find what's the sum of 13/3 and 2/7.
step 2 Compare the denominators of fractions 13/3 and 2/7 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 13/3 and 2/7 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 13/3 and 2/7:
The LCM of 3 and 7 is 21.
step 4 Write the fractions 13/3 and 2/7 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 13/3 + 2/7
= [(13 x 21)/(3 x 21)] + [(2 x 21)/(7 x 21)]
step 5 Simplify the expression to have common denominator:
= 91/21 + 6/21
step 6 Take the common values out and rewrite the above expression like the below:
= 1/21 x (91/1 + 6/1)
= 1/21 x (91 + 6)
step 7Simplify the above expression further:
= 1/21 x 97
= 97/21
13/3 + 2/7 = 97/21
Hence,
13/3 plus 2/7 as a fraction is 97/21.
13/3 + 2/7 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 13/3
Fraction B: 2/7
What to be found?
(13/3)+(2/7) = ?
Find what's the sum of 13/3 and 2/7.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (13 x 7), find the product of numerator of Fraction B and denominator of Fraction A (2 x 3), and find the product of both denominators of Fraction A and Fraction B (3 x 7) and rewrite the equation as like the below:
= (13 x 7) + (2 x 3)/(3 x 7)
step 3 Simplify and rewrite the fraction:
= (91 + 6)/21
