By simplifying the fraction addition expression becomes 53/20.
The below workout with step by step calculation shows how to find the equivalent fraction between 7/5 and 5/4 by adding two fractions with different, unequal or unlike denominators. The sum in fraction form for 7/5 plus 5/4 can be obtained by using anyone of the two methods below.
1. LCM method
2. Cross multiplication method.
7/5+5/4 using LCM Method:
What is 7/5 plus 5/4 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/5
Fraction B: 5/4
What to be found?
7/5+5/4 = ?
Find what's the sum of 7/5 and 5/4.
step 2 Compare the denominators of fractions 7/5 and 5/4 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 7/5 and 5/4 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 5/4:
The LCM of 5 and 4 is 20.
step 4 Write the fractions 7/5 and 5/4 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
=7/5+5/4
=(7 x 20)/(5 x 20)+(5 x 20)/(4 x 20)
step 5 Simplify the expression to have common denominator:
=28/20+25/20
step 6 Take the common values out and rewrite the above expression like the below:
=1/20 x (28/1+25/1)
=1/20 x (28 + 25)
step 7Simplify the above expression further:
=1/20 x 53
=53/20
7/5+5/4=53/20
Hence,
7/5 plus 5/4 equals to 53/20 in fraction.
7/5+5/4 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/5
Fraction B: 5/4
What to be found?
7/5+5/4 = ?
Find what's the sum of 7/5 and 5/4.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (7 x 4), find the product of numerator of Fraction B and denominator of Fraction A (5 x 5), and find the product of both denominators of Fraction A and Fraction B (5 x 4) and rewrite the equation as like the below:
= (7 x 4) + (5 x 5)/(5 x 4)
step 3 Simplify and rewrite the fraction:
= (28 + 25)/20
7/5+5/4 = 53/20
Hence,
7/5 plus 5/4 = 53/20
