Learn how to find what is 1/1 plus 1/78 in fraction form just in a few minutes. We have covered the easiest method to write 1/1 + 1/78 as a fraction and decimal.
Summary: 1/1 plus 1/78 = 79/78
Since both fractions have unequal denominators, 1/1 plus 1/78 is an unlike fractions addition. For adding unlike fractions, you have to first find the equivalent fractions for fraction 1/1 and fraction 1/78 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 1 and 78. 78 is the LCM of 1 and 78. Multiplying the LCM 78 with the numerators and denominators of both fractions (1/1 x 78/78) + (1/78 x 78/78), and simplify further in order to have the common denominator. So the equivalent fraction for 1/1 is 78/78 and for 1/78 is 1/78. By simplifying this fraction addition 78/78 + 1/78, it becomes 79/78.
The below workout with step by step calculation shows how to find the equivalent fraction between 1/1 and 1/78 by adding two fractions with different, unequal or unlike denominators. The sum in fraction form for 1/1 plus 1/78 can be obtained by using anyone of the two methods below.
1. LCM method
2. Cross multiplication method.
(1/1) + (1/78) using LCM Method:
What is 1/1 plus 1/78 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/1
Fraction B: 1/78
What to be found?
(1/1) + (1/78) = ?
Find what's the sum of 1/1 and 1/78.
step 2 Compare the denominators of fractions 1/1 and 1/78 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 1/1 and 1/78 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 1/1 and 1/78:
The LCM of 1 and 78 is 78.
step 4 Write the fractions 1/1 and 1/78 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 1/1 + 1/78
= [(1 x 78)/(1 x 78)] + [(1 x 78)/(78 x 78)]
step 5 Simplify the expression to have common denominator:
= 78/78 + 1/78
step 6 Take the common values out and rewrite the above expression like the below:
= 1/78 x (78/1 + 1/1)
= 1/78 x (78 + 1)
step 7Simplify the above expression further:
= 1/78 x 79
= 79/78
1/1 + 1/78 = 79/78
Hence,
1/1 plus 1/78 as a fraction is 79/78.
1/1 + 1/78 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/1
Fraction B: 1/78
What to be found?
(1/1)+(1/78) = ?
Find what's the sum of 1/1 and 1/78.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (1 x 78), find the product of numerator of Fraction B and denominator of Fraction A (1 x 1), and find the product of both denominators of Fraction A and Fraction B (1 x 78) and rewrite the equation as like the below:
= (1 x 78) + (1 x 1)/(1 x 78)
step 3 Simplify and rewrite the fraction:
= (78 + 1)/78
1/1 + 1/78 = 79/78
Hence,
1/1 plus 1/78 in fraction is 79/78
