1.85乘0.17加0.83乘0.83简算怎么算,得多少要算式,在下午1点半前,

=(1.02+0.83)×0.17+0.83×0.83
=1.02×0.17+0.83×0.17+0.83×0.83
=1×0.17+0.02×0.17+0.83×(0.17+0.83)
=0.17+0.0034+0.83×1
=1.0034

1.85×0.17+0.83=1.85×0.17+1-0.17=1+0.17×(1.85-1)=1+0.17×0.85
=1-0.1445=0.8555

你是不是题目抄错了.
1.83*0.17+0.83*0.83
=（1+0.83）*0.17+0.83*0.83
=0.17+0.83*0.17+0.83*0.83
=0.17+0.83*（0.17+0.83）
=0.17+0.83
=1

1.85x0.17+0.83x0.83
=1.85x0.17+0.83x(1-0.17)
=1.85x0.17-0.83x0.17+0.83
=(1.85-0.83)x0.17+0.83
=1.02x0.17+0.83
=(1+0.02)x0.17+0.83
=0.17+0.83+0.0034
=1+0.0034
=1.0034
