Finding Average of 5/80, 23/78, 7 9/85
Given fractions are 5/80,23/78,604/85
The LCM of 80,78,85 (denominators of the fractions) is 53040
Arrange the Inputs 80,78,85 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 | 80, 78, 85 |
5 | 40, 39, 85 |
8, 39, 17 |
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 5 x 8 x 39 x 17 = 53040
Therefore, LCM of 80,78,85 is 53040
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(80, 78) = 2
LCM(80, 78) = ( 80 x 78 ) / 2
LCM(80, 78) = 6240 / 2
LCM(80, 78) = 3120
Step2:
Here we consider the LCM from the above i.e. 3120 as first number and the next as 85
The formula of LCM is LCM(a,b) = ( a x b) / GCF(a,b)
GCF(3120, 85) = 5
LCM(3120, 85) = ( 3120 x 85 ) / 5
LCM(3120, 85) = 265200 / 5
LCM(3120, 85) = 53040
LCM of 80,78,85 is 53040
The least common Multiple (LCM) is: 53040.
Rewriting as equivalent fractions with the LCM:
= 3315/53040,15640/53040,376896/53040
= 3315+15640+376896/53040
Totaling the numerator:
395851/53040
Dividing by the number of values: 3
The given fractions are 395851/53040 and 3/1
On dividing the both fractions,395851/53040 ÷ 3/1
Then the denominator of the first fraction i.e., 53040 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:
395851/53040 ÷ 3/1 = 395851 x 1/53040 x 3
On Multiplying the denominators and the numerators,the fraction value we get,
395851/159120
Result: 395851/159120
Average of fraction = 395851/159120
