101乘以七分之一减七分之一 四十七分之六乘以四十八 七分之一乘以三十四乘以七乘以十七分之二（简便算法，三题都是）

简单的说就是101个七分之1减去1个七分之一，等于7分之100
47分之6乘以48等于47分之6乘以（50-2）等于47分之（300-12）等于47分之288
七分之一乘以三十四乘以七乘以十七分之二等于7分之1乘以7再乘以34再乘以17分之2等于4
47分之6乘以48等于47分之6乘以（50-2）等于47分之（300-12）等于47分之288
七分之一乘以三十四乘以七乘以十七分之二等于7分之1乘以7再乘以34再乘以17分之2等于4

101乘以七分之一减七分之一
101X1/7— 1/7
= （101—1)X1/7
=100X1/7
=100/7
四十七分之六乘以四十八
6/47 X48
= 6/47 X(47+1)
=6/47 X47+6/47 X1
=6+6/47
=6又6/47
七分之一乘以三十四乘以七乘以十七分之二
1/7 X 34 X 7 X 2/17
=(1/7 X 7) X(34X 2/17)
=1X4

101x1/7-1/7
=(101-1）x1/7
=100x1/7
=100/7
6/47x48
=6/47x(47+1)
=6+6/47
=6又47分之6
1/7x34x7x2/17
=1/7x7x34x2/17
=1x4
=4
=(101-1）x1/7
=100x1/7
=100/7
6/47x48
=6/47x(47+1)
=6+6/47
=6又47分之6
1/7x34x7x2/17
