你好
简便计算过程如下
0.78×91.6+6.2×9.16
=7.8×0.1×91.6+6.2×9.16
=7.8×9.16+6.2×9.16
=(7.8+6.2)×9.16
=14×9.16
=(10+4)×9.16
=10×9.16+4×9.16
=91.6+36.64
=128.24
望采纳
0.78×91.6+6.2×9.16
=7.8×9.16+6.2×9.16
= 9.16×(7.8+6.2)
=9.16×14
=128.24
倍数换算。
0.78×91.6+6.2×9.16
=7.8×9.16+6.2×9.16
=(7.8+6.2)x9.16
=14x9.16
=128.24
=9.16*(7.8+6.2)
=9.16*14
=9.16*(10+4)
=91.6+9.16*4
=91.6+(9+0.16)*4
=91.6+36+0.64
=128.24
=91.6×(0.78+0.62)
=91.6×1.4
=(92-0.4)×(1+0.4)
=92+36.8-0.4-0.16
=128.24
