Answer 1

455×7又3/5+171÷(5/96)+43.3×76
=455*38/5+171*96/5+433*7.6
=91*38+171*96/5+433*8-433*0.4
=90*38+38+342*48/5+3200+240+24-160-12-1.2
=3600-180+38+（342*50-342*2）/5+3464-172-1.2
=3458+3420-342*0.4+3362-70-1.2
=6878-684*0.2+3300-8-1.2
=6878-136.8+3292-1.2
=6741+0.2+3291-0.2
=6741+3291
=9942+90
=9932+100
=10032

Answer 2

455×7又3/5+171÷（5/96）+43.3×76
=455×7.6+433×7.6+171×（96/5）
=（455+433）×7.6+171×19.2
=888×7.6+19×9×0.4×48
=888×7.6+（19×0.4）×48×9
=888×7.6+7.6×432
=（888+432）×7.6
=1320×7.6
=10032
