87/72, 21/32, 7 7/2 Fractions Average can be found easily using the online tool Fractions Average Calculator and get step by step procedure involved.
Given fractions are 87/72,21/32,21/2
Arrange the Inputs 72,32,2 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 | 72, 32, 2 |
| 2 | 36, 16, 1 |
| 2 | 18, 8, 1 |
| 9, 4, 1 |
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 2 x 2 x 9 x 4 x 1 = 288
Therefore, LCM of 72,32,2 is 288
The least common Multiple (LCM) is: 288.
Rewriting as equivalent fractions with the LCM:
= 348/288,189/288,3024/288
= 348+189+3024/288
Totaling the numerator:
3561/288
Reducing the fraction:
1187/96
Dividing by the number of values: 3
The given fractions are 1187/96 and 3/1
On dividing the both fractions,1187/96 ÷ 3/1
Then the denominator of the first fraction i.e., 96 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:
1187/96 ÷ 3/1 = 1187 x 1/96 x 3
On Multiplying the denominators and the numerators,the fraction value we get,
1187/288
Result: 1187/288
Average of fraction = 1187/288
