Finding Average of 21/51, 3/8, 45/99
Given fractions are 21/51,3/8,45/99
The LCM of 51,8,99 (denominators of the fractions) is 13464
Arrange the Inputs 51,8,99 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.
| 3 | 51, 8, 99 |
| 17, 8, 33 |
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. 3 x 17 x 8 x 33 = 13464
Therefore, LCM of 51,8,99 is 13464
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(51, 8) = 1
LCM(51, 8) = ( 51 x 8 ) / 1
LCM(51, 8) = 408 / 1
LCM(51, 8) = 408
Step2:
Here we consider the LCM from the above i.e. 408 as first number and the next as 99
The formula of LCM is LCM(a,b) = ( a x b) / GCF(a,b)
GCF(408, 99) = 3
LCM(408, 99) = ( 408 x 99 ) / 3
LCM(408, 99) = 40392 / 3
LCM(408, 99) = 13464
LCM of 51,8,99 is 13464
The least common Multiple (LCM) is: 13464.
Rewriting as equivalent fractions with the LCM:
= 5544/13464,5049/13464,6120/13464
= 5544+5049+6120/13464
Totaling the numerator:
16713/13464
Reducing the fraction:
1857/1496
Dividing by the number of values: 3
The given fractions are 1857/1496 and 3/1
On dividing the both fractions,1857/1496 ÷ 3/1
Then the denominator of the first fraction i.e., 1496 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:
1857/1496 ÷ 3/1 = 1857 x 1/1496 x 3
On Multiplying the denominators and the numerators,the fraction value we get,
1857/4488
Result: 619/1496
Average of fraction = 619/1496
