{ [ 0,75 + 0,( 6 ) ] : 17 + 0,5 : 1 / 0, 3 + 0, 01(6) } × 48 =

0,75 = 75 / 100 = 3 / 4

0,( 6) = 6 / 9 = 2 / 3

0,5 = 5 / 10 = 1 / 2

0,3 = 3 / 10

0,01(6) = ( 16 - 1 ) / 900 = 15 / 900 = 5 / 300 = 1 / 60

= { [ 3 / 4 + 2 / 3] : 17 + 1 / 2 × 10 / 3 + 1 / 60 } × 48 =

= [ ( 9 / 12 + 8 / 12 ) : 17 + 5 / 3 + 1 / 60 ] × 48 =

= ( 17 / 12 × 1 / 17 + 5 / 3 + 1 / 60 ) × 48 =

= ( 1 / 12 + 5 / 3 + 1 / 60 ) × 48 =

= ( 5 + 100 + 1 ) / 60 × 48 =

= 106 / 10 × 8 =

= 424 / 5 =
