参考答案:0.8888*0.6+0.2222*7.6
=0.2222(4 * 0.6 + 7.6)
=0.2222(2.4 + 7.6)
=2.222
2.4*20又5分之3+33.1*7.6
=2.4 * 20.6 + 33.1 * 7.6
=20.6(2.4 + 7.6) + 12.5 * 7.6
=206 + 25/2 * 38/5
=206 + 5 * 19
=206 + 95
=301
4.25*166-42又2分之1*14.2+24*5.75
=4.25 * 166 - 42.5 * 14.2 + 24 * 5.75
=4.25(166 - 142) + 24(10 - 4.25)
=4.25(24 - 24) + 240
=240
3又5分之3*14.4+9.3*32+3.21*36
=36(1.44 + 3.21) + 9.3 * 32
=36 * 4.65 + 4.65 * 64
= 465
998*563+8126
=(1000 - 2) * 563 + 8126
=563000 - 1126 + 8126
=570000
229又11分之1除46又44分之1
=2520/11 / (2025/44)
=2520/11 * 44/2025
=2520 * 4 / 2025
=4 * 5 * 7 * 8 * 9 / (5 * 5 * 9 * 9)
=4 * 7 * 8 / (5 * 9)
=224 / 45
