Question

2.92×12.5怎么简便计算？

Answer 1

2.92×12.5=2.92×（12+0.5）
=2.92×12+2.92×0.5
=35.04+1.46
=36.5

Answer 2

2.92×12.5
=2.92×（100÷8）
=2.92÷8×100
=0.365×100
=36.5

Answer 3

计算：
2.92×12.5
=2.92×(10+2+0.5)
=2.92×10+2.92×2+2.92×0.5
=29.2+5.84+1.46
=29+5+1+(0.2+0.8+0.4)+(0.04+0.06)
=35+1.4+0.1
=36.5
答题完毕。

Answer 4

2.92×12.5
＝（3-0.08）×12.5
＝3×12.5-0.08×12.5
＝3×（10+2.5）-1
＝30+7.5-1
＝36.5

Answer 5

你好，根据你的题意，这道题我认为应该这样做最简便
2.92×12.5
＝（3-0.08）×12.5
＝3×12.5-0.08×12.5
=37.5-1
=36.5
以上仅供参考，希望能对你有所帮助
