In a molecule of tetraborane $\left(B_4{H}_{10}\right)$  , if the number of$2c-2e$   bonds is ‘p’ and the number of $3c-2e$ bonds is ‘q’, report the value of  $\frac{p}{q}$ (p divided by q)

Structure of  ${\text{B}}_{\text{4}}{\text{H}}_{\text{10}}:$
 
  $\text{S}=\text{B}-\text{H}-\text{B}$              $3c-2e\text{\hspace{0.17em}\hspace{0.17em}bonds\hspace{0.17em}\hspace{0.17em}}=4$
  $\text{t}=\text{B}-\text{B}-\text{B}$                 $3c-2e\text{\hspace{0.17em}\hspace{0.17em}bonds\hspace{0.17em}\hspace{0.17em}}=0$
