41.2×9.2+537×0.08怎么简便计算吗?
= 41.2×9.2+(412+125)×0.08
= 41.2×9.2+41.2×0.8+12.5×0.8
= 41.2×(9.2+0.8)+12.5×0.8
= 412+10
= 422
望采纳 谢谢~~
= 41.2×9.2+(412+125)×0.08
= 41.2×9.2+41.2×0.8+12.5×0.8
= 41.2×(9.2+0.8)+12.5×0.8
= 412+10
= 422

解:41.2x9.2+537x0.08
= 41.2x9.2+(412+125)x0.08
= 41.2x9.2+41.2x0.8+12.5x0.8
= 41.2x(9.2+0.8)+12.5x0.8
= 412+10
= 422
= 41.2x9.2+(412+125)x0.08
= 41.2x9.2+41.2x0.8+12.5x0.8
= 41.2x(9.2+0.8)+12.5x0.8
= 412+10
= 422
