The below workout with step by step calculation shows how to find the equivalent fraction between 2/7 and 1/78 by adding two fractions with different, unequal or unlike denominators. The sum in fraction form for 2/7 plus 1/78 can be obtained by using anyone of the two methods below.
1. LCM method
2. Cross multiplication method.
(2/7) + (1/78) using LCM Method:
What is 2/7 plus 1/78 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/7
Fraction B: 1/78
What to be found?
(2/7) + (1/78) = ?
Find what's the sum of 2/7 and 1/78.
step 2 Compare the denominators of fractions 2/7 and 1/78 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 2/7 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 2/7 and 1/78:
The LCM of 7 and 78 is 546.
step 4 Write the fractions 2/7 and 1/78 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 2/7 + 1/78
= [(2 x 546)/(7 x 546)] + [(1 x 546)/(78 x 546)]
step 5 Simplify the expression to have common denominator:
= 156/546 + 7/546
step 6 Take the common values out and rewrite the above expression like the below:
= 1/546 x (156/1 + 7/1)
= 1/546 x (156 + 7)
step 7Simplify the above expression further:
= 1/546 x 163
= 163/546
2/7 + 1/78 = 163/546
Hence,
2/7 plus 1/78 as a fraction is 163/546.
2/7 + 1/78 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/7
Fraction B: 1/78
What to be found?
(2/7)+(1/78) = ?
Find what's the sum of 2/7 and 1/78.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (2 x 78), 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 78) and rewrite the equation as like the below:
= (2 x 78) + (1 x 7)/(7 x 78)
step 3 Simplify and rewrite the fraction:
= (156 + 7)/546
2/7 + 1/78 = 163/546
