30:([tex] \frac{1}{10} [/tex] - [tex] \frac{1}{10} [/tex] :3)=
30:([tex] \frac{1}{10} [/tex] - [tex] \frac{1}{10} [/tex] *[tex] \frac{1}{3} [/tex] =
30:([tex] \frac{1}{10} [/tex] - [tex] \frac{1}{30} [/tex])=
30:([tex] \frac{3}{30} [/tex] - [tex] \frac{1}{30} [/tex])=
30:[tex] \frac{2}{30} [/tex]=
30*[tex] \frac{30}{2} [/tex]=
30*15=
450

























30:(1/10 -1/10 :3)=
30:( 1/10 -1/10*1/3)=450
30:(1/10 -1/30)=
30:(3/30-1/3/)=
30: 2/30=
30:1/15=
30*15/1=450
