What is 30% of 195?

30% of 195

=30/100*195

=3/10*195

=585/10

=117/2

=58.5

very simple :

1.)      $${\mathtt{195}}{\mathtt{\,\times\,}}{\mathtt{30}}\% = {\frac{{\mathtt{117}}}{{\mathtt{2}}}} = {\mathtt{58.5}}$$

 

2.)   30% = 30/100 = 0,3   =>    $${\mathtt{195}}{\mathtt{\,\times\,}}{\mathtt{0.3}} = {\frac{{\mathtt{117}}}{{\mathtt{2}}}} = {\mathtt{58.5}}$$

Another way.

 

$${\frac{{\mathtt{195}}}{{\mathtt{10}}}}{\mathtt{\,\times\,}}{\mathtt{3}} = {\frac{{\mathtt{117}}}{{\mathtt{2}}}} = {\mathtt{58.5}}$$
