Question

arithmetic mean of 1/2 and 1/3

Answer 1

Arithmetic mean of 1/2 and 1/3 is 5/12.

Given:

• $\frac{1}{2} \: and \: \frac{1}{3}$

To find:

• Find arithmetic mean.

Solution:

Formula to be used:

If two numbers 'a' and 'b' are given,then arithmetic mean of numbers is

$\bf Mean=\frac{a + b}{2}$

Step 1:

Find the sum of both numbers.

As given numbers are 1/2 and 1/3.

$Sum = \frac{1}{2} + \frac{1}{3}$

or

$Sum = \frac{(1 \times 3 )+ (1 \times 2)}{6}$

or

$\bf Sum = \frac{5}{6}$

Step 2:

Find arithmetic mean.

$Mean = \frac{ \frac{5}{6} }{ 2}$

or

$\bf Mean = \frac{5}{12}$

Thus,

Arithmetic mean of 1/2 and 1/3 is 5/12.
