Calculating mean and median for whole numbers are pretty easy. While the fractional numbers are little more calculated.
Step-by-step explanation: For example let us take:
2/3, 3/4, 5/4
Mean: To find the mean of above number, we shall calculate the LCM of the denominator:
LCM of 3,4,4 is 12
Now, to calculate the mean, follow a simple formula:
Average value ÷ Number of value
that is: 2×4 + 3×3 + 5×3 ÷ 12 (÷3)
= 8+9+15÷12 (÷3)
= 2.6÷3
=0.8
therefore the required mean for given fraction is 0.8
Median: To find the median of a fraction, first we shall deduce the fraction in the decimal numbers
2/3 = 0.6
3/4 = 0.75
5/4 = 1.25
replace the decimals into ascending order
0.6, 0.75, 1.25
The middle most value is our required median
Median of given fraction is 0.75
