  1. ( 750 × 360 × 55 ) : ( 15 × 12 × 11 )
    = ( 750 : 15 ) × ( 360 : 12 ) × ( 55 : 11 )
    = 50 × 30 × 5
    = 1500 × 5
    = 7500

  2. (750 × 360 × 55) ÷ (15 × 12 × 11)
    = 750 × 360 × 55 ÷ 15 ÷ 12 ÷ 11
    = ( 750 ÷ 15 ) × ( 360 ÷ 12 ) × ( 55 ÷ 11 )
    = 50 × 30 × 5 
    = 1500 × 5
    = 7500
