✔ 最佳答案
1.0.25X60X4-0.4X37.5X2-4X1.25X4.8
=60x(0.25x4)-4x(37.5x0.2)-4x0.6x(1.25x8)
=60x1-4x7.5-4x0.6x10
=60-30-24
=6
2.
(24024X2.7X16)/(108X91X0.3X88)
=(264x9x2)/(108x1x1x11)
=(24x18)/108
=(4x18)/18
=4
3.
39X77X37=111111
74X66X91=111111x2x(6/7)x(39/91)
74X66X91=222222x(234/637)
74X66X91=81632.571
4.
(1X2X3X4X5X6X7X8X9X10X11)/(27X25X24X22)
