Answer 1

0.62乘以3.2加6.2乘以0.32简便运算怎么做

解：解：根据已知条件，计算：

0.62x3.2+6.2x0.32

=0.62x10x3.2÷10+6.2x0.32

=6.2x0.32+6.2x0.32

=6.2x(0.32+0.32)

=6.2x0.64

=6.2x8x0.08

=49.6x0.08

=3.968

Answer 2

根据题意可得:
0.62x3.2+6.2x0.32
=0.62x3.2+6.2÷10x0.32
=0.62x3.2+0.62x0.32
=2x0.62x3.2
=1.24x3.2
=(1.25-0.01)x3.2
=1.25x3.2-0.01x3.2
=1.25x8x0.4-0.01x3.2
=4-0.032
=3.968

Answer 3

0.62*3.2+6.2*0.32
=3.2*0.62+3.2*0.62
=3.2*（0.62+0.62）
=3.2*1.24
=3.968

Answer 4

解：依题意得

---

0.62×3.2+6.2×0.32

---

=6.2×0.1×3.2+6.2×0.32

---

=6.2×（0.32+0.32）

---

=6.2×（0.6+0.04）

---

=6.2×0.6+6.2×0.04

---

=3.968

Answer 5

0.62×3.2+6.2×0.32
=0.62×3.2+0.62×3.2
=2×0.62×3.2
=0.62×6.2
=0.1×6.2^2
=3.844
