简便计算:7.59ⅹ11.8-18ⅹ0.759？

Answer 1

答题如下：
7.59ⅹ11.8-18ⅹ0.759 = 7.59 x 11.8 - 1.8 x 10 x 0.759 = 7.59 x 11.8 - 7.59 x 1.8 = 7.59 x (11.8 - 1.8) = 7.59 x 10 = 75.9

Answer 2

7.59×11.8－18×0.759

---

=7.59×11.8－1.8×7.59

---

=7.59×(11.8－1.8)

---

=7.59×10

---

=75.9

Answer 3

有乘法和加减法的算式，简便计算的思路是，找出相同的乘数。如果没有，就把原来的乘数转化成相同的乘数。然后运用分配律。
7.59x11.8-18x0.759
=7.59x11.8-(18/10)x(0.759x10)
=7.59x11.8-1.8x7.59
=7.59x(11.8-1.8)
=7.59x10

=75.9
希望对你有所帮助。

Answer 4

简便计算是改变小时点位置，提取公约数7.59得
7.59x11.8-18x0.759
=7.59x(11.8-1.8)
=7.59x10
=75.9
