Learn how to find what is 5/7 plus 1/2 in fraction form just in a few minutes. We have covered the easiest method to write 5/7 + 1/2 as a fraction and decimal.
Summary: 5/7 plus 1/2
Since both the fractions have the unequal denominators, you have to find the equivalent fractions for 5/7 and 1/2 having identical denominators before starting adding the fractions. Find the LCM of denominators, 14 is the LCM of 7 and 2. Multiply the LCM 14 with all the numerators and denominators of both fractions (5/7 x 14/14) + (1/2 x 14/14) and simplify further in order to have the common denominators. By simplifying the fraction addition expression becomes 17/14.
The below workout with step by step calculation shows how to find the equivalent fraction between 5/7 and 1/2 by adding two fractions with different, unequal or unlike denominators. The sum in fraction form for 5/7 plus 1/2 can be obtained by using anyone of the two methods below.
1. LCM method
2. Cross multiplication method.
5/7+1/2 using LCM Method:
What is 5/7 plus 1/2 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 5/7
Fraction B: 1/2
What to be found?
5/7+1/2 = ?
Find what's the sum of 5/7 and 1/2.
step 2 Compare the denominators of fractions 5/7 and 1/2 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 5/7 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 5/7 and 1/2:
The LCM of 7 and 2 is 14.
step 4 Write the fractions 5/7 and 1/2 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
=5/7+1/2
=(5 x 14)/(7 x 14)+(1 x 14)/(2 x 14)
step 5 Simplify the expression to have common denominator:
=10/14+7/14
step 6 Take the common values out and rewrite the above expression like the below:
=1/14 x (10/1+7/1)
=1/14 x (10 + 7)
step 7Simplify the above expression further:
=1/14 x 17
=17/14
5/7+1/2=17/14
Hence,
5/7 plus 1/2 equals to 17/14 in fraction.
5/7+1/2 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 5/7
Fraction B: 1/2
What to be found?
5/7+1/2 = ?
Find what's the sum of 5/7 and 1/2.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (5 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:
= (5 x 2) + (1 x 7)/(7 x 2)
step 3 Simplify and rewrite the fraction:
= (10 + 7)/14
5/7+1/2 = 17/14
Hence,
5/7 plus 1/2 = 17/14
