Question

find the average of 1 upon 2, 1 upon 3,1 upon 4, 1 upon 6

Answer 1

So, the question is

$\frac{1}{2} + \frac{1}{3} + \frac{1}{4} + \frac{1}{6}$
On taking the L.C.M.
We get,

12 as the L.C.M.

So, then

$\frac{6 + 4 + 3 + 2}{12}$
On adding up,

$\frac{15}{12}$
So, the answer is 5/4

Since there were 4 fractions

So, the average is

=》5/4/4

=》5/4×4

=》5/16

Hope it helps you.

Answer 2

The  average of$\dfrac{1}{2} ,\dfrac{1}{3} ,\dfrac{1}{4} and \dfrac{1}{6}$ is $\dfrac{5}{16}$.

Step-by-step explanation:

We have,

$\dfrac{1}{2} ,\dfrac{1}{3} ,\dfrac{1}{4} and \dfrac{1}{6}$

To find, the average = ?

We know that,

Average = $\dfrac{Sum of all observations}{Total number of observations}$

∴ Average = $\dfrac{\dfrac{1}{2}+\dfrac{1}{3}+\dfrac{1}{4}+\dfrac{1}{6}}{4}$

The LCM of 2, 3, 4 and 6 is 12.

$= \dfrac{\dfrac{6+4+3+2}{12}}{4}$

$= \dfrac{\dfrac{15}{12}}{4}$

$= \dfrac{\dfrac{5}{4}}{4}=\dfrac{5}{16}$

Hence, the  average of $\dfrac{1}{2} ,\dfrac{1}{3} ,\dfrac{1}{4} and \dfrac{1}{6}$ is $\dfrac{5}{16}$.
