Finding Average of 71/20, 8/5, 20/27
Given fractions are 71/20,8/5,20/27
The LCM of 20,5,27 (denominators of the fractions) is 540
Arrange the Inputs 20,5,27 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.
5 | 20, 5, 27 |
4, 1, 27 |
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. 5 x 4 x 1 x 27 = 540
Therefore, LCM of 20,5,27 is 540
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(20, 5) = 5
LCM(20, 5) = ( 20 x 5 ) / 5
LCM(20, 5) = 100 / 5
LCM(20, 5) = 20
Step2:
Here we consider the LCM from the above i.e. 20 as first number and the next as 27
The formula of LCM is LCM(a,b) = ( a x b) / GCF(a,b)
GCF(20, 27) = 1
LCM(20, 27) = ( 20 x 27 ) / 1
LCM(20, 27) = 540 / 1
LCM(20, 27) = 540
LCM of 20,5,27 is 540
The least common Multiple (LCM) is: 540.
Rewriting as equivalent fractions with the LCM:
= 1917/540,864/540,400/540
= 1917+864+400/540
Totaling the numerator:
3181/540
Dividing by the number of values: 3
The given fractions are 3181/540 and 3/1
On dividing the both fractions,3181/540 ÷ 3/1
Then the denominator of the first fraction i.e., 540 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:
3181/540 ÷ 3/1 = 3181 x 1/540 x 3
On Multiplying the denominators and the numerators,the fraction value we get,
3181/1620
Result: 3181/1620
Average of fraction = 3181/1620
