Question

Divide $15et20$ by $9$ in the scale of twelve.

Answer 1

$\Rightarrow 15=1\times T+5=$seventeen ($\because$ in scale of twelve i.e., 'T')

Seventeen$=1\times 9+8$, We put ${}^{\prime }{1}^{\prime }$ down and take carry $8$

Now,

$8\times T+e=$One hundred and seven

($\because$ 'T' is twelve and 'e' is 'eleven' )

$\therefore 9\times e+8$ We put 'e' down and tale carry $8$

Now,

$8\times T+t=$One hundred and six

$9\times e+7$ and so on
