Question

十三分之三乘三十七分之二十六加三十七分之五用简便运算怎么做?

Answer 1

3/13×26/37+5/37
=（3×2）/37+5/37
=6/37+5/37
=11/37
根据运算法则差没，先计算行好乘法，再计算加法。计算乘法时可以先约档庆铅分再计算。

Answer 2

十三分亮并族之三乘三十七分之二十六加三十七分之五简便运算怎么做 ？敬弊
3/13×26/37＋5/蔽袭37
＝3×2/37＋5/37
＝11/37
3/13×26/37＋5/37＝11/37。

Answer 3

解：简便方法运算
3/13X26/37+5/37=3/1X2/37+5/37=6/37+5/37=11/37，(3/13X26/37时3/13的分母13与26/桥闷闹37的分子敏罩罩漏26约分，就等于3/1X2/37)

Answer 4

3/磨谈13x26/升祥37+5/瞎笑碰37
=1/37x(3/13x26+5)
=1/37x(6+5)
=11/37

Answer 5

3/13×26/37+5/37
=6/37+5/37
=11/37
