(1):3加3/4除以3/4加三的商除以七乘1/6除以七乘1/6...

1/6除以中括号9/17乘以括号3/4加2/3括号中括号 解: 1/6÷[9/17×(3/4+2/3)] =1/6÷(9/17×17/12) =1/6÷3/4 =2/9

1/4×(-6/7-3 3/4)÷(-11) =1/4×(-6/7-15/4)×(-1/11) =1/4×45/14×(-1/11) =45/56×(-1/11) =-45/616

你好,很高兴为你解答 1/6÷[9/17x(3/4+2/3)] =1/6÷(9/17x17/12) =1/6x4/3 =2/9(表示9分之2) 满意采纳哦!

请尊重我的劳动成果,请采纳!

用简便方法计算 (1/27-1/36)÷1/9 =1/27÷1/9-1/36÷1/9 =1/3-1/4 =1/12 3/5×1/6+7/5÷6 =3/5×1/6+7/5×1/6 =(3/5+7/5)×1/6 =2×1/6 =1/3 7÷5×(5/7+5/28) =7/5×(5/7+5/28) =7/5×5/7+7/5×5/28 =1+1/4 =1又1/4 3/4×1/2÷3/4×2 =(3/4÷3/4)×(1/2...

一加5/8除以5/6乘以8/9。 1+5/8÷5/6×8/9 =1+5/8×6/5×8/9 =1+2/3 =1又2/3 括号5/6减3/4乘以4/15。 (5/6-3/4)×4/15 =1/12×4/15 =1/45 括号3/4减3/4乘5/6除4/3。 (3/4-3/4)×5/6÷4/3 =0×5/6÷4/3 =0

2/3-(5/6-3/4)除3/8 =2/3-1/12除3/8=2/3-2/9=4/9 5/14除【6/7乘(4/9+1/6)】=5/14除【6/7乘11/18】=5/14除11/21=15/22

(1/6+1/2)/6/7=2/3 *7/6=7/9 [4-(3/4+3/8]*4/29=(4-9/8)*4/29=23/8 *4/29=23/58 (5/9) / (5/13)+1/3=13/9+1/3=16/9

【7/4】乘以4/7 等于八乘以【1/8】 等于3/5除以【3/5】 等于【6÷】六 等于4/9加【5/9】 等于一
