添上四则运算符号或括号,使下列等式成立.(题目在下面)1 2/1 3/1 6/1 =0 1 2/1 3/1 6/1 =1 1 2/1 3/1 6/1 =2 1 2/1 3/1 6/1 =3
添上四则运算符号或括号,使下列等式成立.(题目在下面)
1 - 2/1- 3/1- 6/1 =0
1+ 2/1 - 3/1 - 6/1 =1
1 + 2/1 + 3/1 + 6/1 =2
(1 +2/1) ×3/1÷ 6/1 =3
1- 2/1 -3/1 -6/1 =0
1- 2/1 +3/1 +6/1 =1
1+ 2/1 +3/1+ 6/1 =2
(1- 2/1) ÷(3/1 -6/1 )=3
1- 2/1 - 3/1 - 6/1 =0
1 ×(2/1 + 3/1 + 6/1) =1
1+2/1 +3/1+ 6/1 =2
1× 2/1 ÷( 3/1 - 6/1) =3
祝学习进步,望采纳(*^__^*)
到底是2/1 3/1 6/1 还是1/2 1/3 1/6,前者就是整数还写什么分数形式
2/1表示二分之一吧
1 - (2/1 + 3/1 + 6/1) =0
1 + (2/1 - 3/1 - 6/1) =1
1 + 2/1 + 3/1 + 6/1 =2
1 × 2/1 ÷ (3/1 - 6/1) =3
