Summary: 7/4 plus 7/19 = 161/76
Since both fractions have unequal denominators, 7/4 plus 7/19 is an unlike fractions addition. For adding unlike fractions, you have to first find the equivalent fractions for fraction 7/4 and fraction 7/19 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 4 and 19. 76 is the LCM of 4 and 19. Multiplying the LCM 76 with the numerators and denominators of both fractions (7/4 x 76/76) + (7/19 x 76/76), and simplify further in order to have the common denominator. So the equivalent fraction for 7/4 is 133/76 and for 7/19 is 28/76. By simplifying this fraction addition 133/76 + 28/76, it becomes 161/76.
The below workout with step by step calculation shows how to find the equivalent fraction between 7/4 and 7/19 by adding two fractions with different, unequal or unlike denominators. The sum in fraction form for 7/4 plus 7/19 can be obtained by using anyone of the two methods below.
1. LCM method
2. Cross multiplication method.
(7/4) + (7/19) using LCM Method:
What is 7/4 plus 7/19 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/4
Fraction B: 7/19
What to be found?
(7/4) + (7/19) = ?
Find what's the sum of 7/4 and 7/19.
step 2 Compare the denominators of fractions 7/4 and 7/19 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 7/4 and 7/19 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 7/4 and 7/19:
The LCM of 4 and 19 is 76.
step 4 Write the fractions 7/4 and 7/19 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 7/4 + 7/19
= [(7 x 76)/(4 x 76)] + [(7 x 76)/(19 x 76)]
step 5 Simplify the expression to have common denominator:
= 133/76 + 28/76
step 6 Take the common values out and rewrite the above expression like the below:
= 1/76 x (133/1 + 28/1)
= 1/76 x (133 + 28)
step 7Simplify the above expression further:
= 1/76 x 161
= 161/76
7/4 + 7/19 = 161/76
Hence,
7/4 plus 7/19 as a fraction is 161/76.
