Question

Find the arithmetic mean of 1by2 and 1by4​

Answer 1

Step-by-step explanation:

$mean = \frac{ \frac{1}{2} + \frac{1}{4} }{2} \\ = \frac{ \frac{ 4 + 2}{4 \times 2} }{2} \\ = \frac{ \frac{6}{8} }{2} \\ = \frac{6}{8} \times \frac{1}{2} \\ = \frac{3}{8}$

Answer 2

Answer:

3/8

Step-by-step explanation:

to find:

arithmetic mean of 1/2 and 1/4

formula :

arithmetic mean  or average both are same.

average of a and b is (a+b)/2

solution:

here a is 1/2

and b is 1/4

adding a and b

a + b = 1/2 + 1/4

        = 3/4

so arithmetic mean of a and b is (3/4) ÷ 2

                                                    = 3/8
