Question

Find the two H.M's between 1/2 and 4/17​

Answer 1

Answer:

$\frac{8}{25}$

Step-by-step explanation:

HM = harmonic mean of a,b  =   $\frac{2ab}{a+b }$

Therefore, H.M of 1/2 and 4/17 =  $\frac{2(1/2)(4/17)}{1/2+ 4/17 }$

                                                   =  $\frac{8}{25}$

Similarly another HM can be found.
