Помогите решить (-0,2+1/3):3,2=

( - 0 , 2 + 1 / 3 ) : 3 , 2 = ( - 2 / 10 + 1 / 3 ) / 3 . 2 = ( - 2 / ( 5 * 2 ) + 1 / 3 ) / 3 . 2 = ( - 1 / ( 5 * 1 ) + 1 / 3 ) / 3 . 2 = ( - 1 / 5 + 1 / 3 ) / 3 . 2 = ( - 15 / 5 * 1 + 15 / 3 * 1 ) / 15 * 3 . 2 = ( - 3 * 1 + 5 * 1 ) / 15 * 3 . 2 = ( - 3 + 5 ) / 15 / 3 . 2 = 2 / 15 / ( 3 целых 2 / 10 ) = 2 / 15 / ( 3 целых 1 / 5) = 2 / 15 / ( ( 3 * 5 + 1 ) / 5 ) = 2 / 15 / ( ( 15 + 1 ) / 5 ) = 2 / 15 / ( 16 / 5 ) = 2 / 15 * ( 5 / 16 ) = ( 2 * 5 ) / ( 15 * 16 ) = ( 1 * 1 ) / ( 3 * 8 ) = 1 / ( 3 * 8 0 = 1 / 24 .
