Finding Average of 30/31, 8/2, 82/78
Given fractions are 30/31,8/2,82/78
The LCM of 31,2,78 (denominators of the fractions) is 2418
Arrange the Inputs 31,2,78 in a horizontal line separated by commas and divide them with a prime number. Note the quotients in the next row and divide with quotients with prime numbers again. Continue the process until you have all co primes in the last.
| 2 | 31, 2, 78 |
| 31, 1, 39 |
As all the numbers left in the last row are co primes you need not do the common division process further.
To obtain the Least Common Multiple, multiply the prime numbers with which you have divided the given numbers and the co primes in the last row i.e. 2 x 31 x 1 x 39 = 2418
Therefore, LCM of 31,2,78 is 2418
Step1:
Let's calculate the LCM of first two numbers
The formula of LCM is LCM(a,b) = ( a x b) / GCF(a,b)
GCF(31, 2) = 1
LCM(31, 2) = ( 31 x 2 ) / 1
LCM(31, 2) = 62 / 1
LCM(31, 2) = 62
Step2:
Here we consider the LCM from the above i.e. 62 as first number and the next as 78
The formula of LCM is LCM(a,b) = ( a x b) / GCF(a,b)
GCF(62, 78) = 2
LCM(62, 78) = ( 62 x 78 ) / 2
LCM(62, 78) = 4836 / 2
LCM(62, 78) = 2418
LCM of 31,2,78 is 2418
The least common Multiple (LCM) is: 2418.
Rewriting as equivalent fractions with the LCM:
= 2340/2418,9672/2418,2542/2418
= 2340+9672+2542/2418
Totaling the numerator:
14554/2418
Reducing the fraction:
7277/1209
Dividing by the number of values: 3
The given fractions are 7277/1209 and 3/1
On dividing the both fractions,7277/1209 ÷ 3/1
Then the denominator of the first fraction i.e., 1209 will comes to the numerator of the second fraction and gets multiplied,
And in the same way,the denominator of the second fraction i.e., 1 will comes to the numerator of the first fraction and gets multiplied:
7277/1209 ÷ 3/1 = 7277 x 1/1209 x 3
On Multiplying the denominators and the numerators,the fraction value we get,
7277/3627
Result: 7277/3627
Average of fraction = 7277/3627
