Learn how to find what is 15/7 plus 1/2 in fraction form just in a few minutes. We have covered the easiest method to write 15/7 + 1/2 as a fraction and decimal.
Summary: 15/7 plus 1/2 = 37/14
Since both fractions have unequal denominators, 15/7 plus 1/2 is an unlike fractions addition. For adding unlike fractions, you have to first find the equivalent fractions for fraction 15/7 and fraction 1/2 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 7 and 2. 14 is the LCM of 7 and 2. Multiplying the LCM 14 with the numerators and denominators of both fractions (15/7 x 14/14) + (1/2 x 14/14), and simplify further in order to have the common denominator. So the equivalent fraction for 15/7 is 30/14 and for 1/2 is 7/14. By simplifying this fraction addition 30/14 + 7/14, it becomes 37/14.
The below workout with step by step calculation shows how to find the equivalent fraction between 15/7 and 1/2 by adding two fractions with different, unequal or unlike denominators. The sum in fraction form for 15/7 plus 1/2 can be obtained by using anyone of the two methods below.
1. LCM method
2. Cross multiplication method.
(15/7) + (1/2) using LCM Method:
What is 15/7 plus 1/2 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 15/7
Fraction B: 1/2
What to be found?
(15/7) + (1/2) = ?
Find what's the sum of 15/7 and 1/2.
step 2 Compare the denominators of fractions 15/7 and 1/2 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 15/7 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 15/7 and 1/2:
The LCM of 7 and 2 is 14.
step 4 Write the fractions 15/7 and 1/2 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 15/7 + 1/2
= [(15 x 14)/(7 x 14)] + [(1 x 14)/(2 x 14)]
step 5 Simplify the expression to have common denominator:
= 30/14 + 7/14
step 6 Take the common values out and rewrite the above expression like the below:
= 1/14 x (30/1 + 7/1)
= 1/14 x (30 + 7)
step 7Simplify the above expression further:
= 1/14 x 37
= 37/14
15/7 + 1/2 = 37/14
Hence,
15/7 plus 1/2 as a fraction is 37/14.
15/7 + 1/2 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 15/7
Fraction B: 1/2
What to be found?
(15/7)+(1/2) = ?
Find what's the sum of 15/7 and 1/2.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (15 x 2), find the product of numerator of Fraction B and denominator of Fraction A (1 x 7), and find the product of both denominators of Fraction A and Fraction B (7 x 2) and rewrite the equation as like the below:
= (15 x 2) + (1 x 7)/(7 x 2)
step 3 Simplify and rewrite the fraction:
= (30 + 7)/14
15/7 + 1/2 = 37/14
Hence,
15/7 plus 1/2 in fraction is 37/14
