H.M is one – fifth larger number . Here 'a' is larger number so,<br>
H.M is one – fifth larger number . Here 'a' is larger number so,<br>
H.M = <math>\frac{1} {5}</math> a<br>
H.M = <math>\frac{1} {5}</math> a<br>
<math>\frac{2ab} {a + b}</math> = <math>\frac{1} {5}</math> a
<math>\frac{2ab} {a + b}</math> = <math>\frac{1} {5}</math> a<br>
Here we cancel 'a' because it is in both side of the equal sign and after cancel 'a' we get,<br>
<math>\frac{2b} {a + b}</math> = <math>\frac{1} {5}</math><br>
