$\large\bold\color{tan}{\underbrace{Explanation}:-}$

$(a)male \: teachers : female \: teachers$

$= > 102 : 51$

$= > (51 \times 2) : (51 \times 1)$

$= > 2 : 1$

$(b)male \: teachers : number \: of \: students$

$= > 102 : 3400$

$= > (34 \times 3) : (34 \times 100)$

$= > 3 : 100$

$(c)female \: teachers : number \: of \: students$

$= > 51 : 3400$

$= > (17 \times 3) : (17 \times 200)$

$= > 3 : 200$
