Calculation: 3.6 × 42.3 × 3.75-12.5 × 0.423 × 28=______ ．

Calculation: 3.6 × 42.3 × 3.75-12.5 × 0.423 × 28=______ ．

3.6 × 42.3 × 3.75-12.5 × 0.423 × 28 = 3.6 × 42.3 × 1.25 × 3-1.25 × 10 × 42.3 × 0.28 = 42.3 × 1.25 × (3.6 × 3-10 × 0.28) = 42.3 × 1.25 × (10.8-2.8) = 42.3 × 1.25 × 8 = 42.3 × (1.25 × 8) = 42.3 × 10 = 423

3,6*42,3*3,75-12,5*0,425*28

3.6×42.3×3.75-12.5×0.423×28
=3.6×42.3×3.75-12.5×42.3×0.28
=42.3×1.25×(10.8-2.8)
=42.3×(1.25×8)
=423

975 times 0.25 + 9 and 4 / 3 times 76-9.75=
Please answer

975 times 0.25 + 9 and 4 / 3 times 76-9.75
=9.75 by 25 + 9.75 by 76-9.75
=9.75 times (25 + 76-1)
=9.75 times 100
=975
