Learn how to find what is 9/8 plus 2/7 in fraction form just in a few minutes. We have covered the easiest method to write 9/8 + 2/7 as a fraction and decimal.
Summary: 9/8 plus 2/7 = 79/56
Since both fractions have unequal denominators, 9/8 plus 2/7 is an unlike fractions addition. For adding unlike fractions, you have to first find the equivalent fractions for fraction 9/8 and fraction 2/7 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 8 and 7. 56 is the LCM of 8 and 7. Multiplying the LCM 56 with the numerators and denominators of both fractions (9/8 x 56/56) + (2/7 x 56/56), and simplify further in order to have the common denominator. So the equivalent fraction for 9/8 is 63/56 and for 2/7 is 16/56. By simplifying this fraction addition 63/56 + 16/56, it becomes 79/56.
The below workout with step by step calculation shows how to find the equivalent fraction between 9/8 and 2/7 by adding two fractions with different, unequal or unlike denominators. The sum in fraction form for 9/8 plus 2/7 can be obtained by using anyone of the two methods below.
1. LCM method
2. Cross multiplication method.
(9/8) + (2/7) using LCM Method:
What is 9/8 plus 2/7 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 9/8
Fraction B: 2/7
What to be found?
(9/8) + (2/7) = ?
Find what's the sum of 9/8 and 2/7.
step 2 Compare the denominators of fractions 9/8 and 2/7 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 9/8 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 9/8 and 2/7:
The LCM of 8 and 7 is 56.
step 4 Write the fractions 9/8 and 2/7 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 9/8 + 2/7
= [(9 x 56)/(8 x 56)] + [(2 x 56)/(7 x 56)]
step 5 Simplify the expression to have common denominator:
= 63/56 + 16/56
step 6 Take the common values out and rewrite the above expression like the below:
= 1/56 x (63/1 + 16/1)
= 1/56 x (63 + 16)
step 7Simplify the above expression further:
= 1/56 x 79
= 79/56
9/8 + 2/7 = 79/56
Hence,
9/8 plus 2/7 as a fraction is 79/56.
9/8 + 2/7 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 9/8
Fraction B: 2/7
What to be found?
(9/8)+(2/7) = ?
Find what's the sum of 9/8 and 2/7.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (9 x 7), find the product of numerator of Fraction B and denominator of Fraction A (2 x 8), and find the product of both denominators of Fraction A and Fraction B (8 x 7) and rewrite the equation as like the below:
= (9 x 7) + (2 x 8)/(8 x 7)
step 3 Simplify and rewrite the fraction:
= (63 + 16)/56
9/8 + 2/7 = 79/56
Hence,
9/8 plus 2/7 in fraction is 79/56
