六年级口算、心算、快速算
一、口算，直接写结果〔50×1分〕=50分
(1) (2) (3) (4) (5) (6) (7) (8) (9) (10)
(11) (12) (13) (14) (15) (16) (17) (18) (19) (20)
求比值：(21) (22) (23) (24) (25) (26) (27) (28) (29) (30)
(31)52 (32)62 (33)72 (34)92 (35)102
(36)112 (37)122 (38)132 (39)142 (40)152
(41)=〔 〕% (42)=〔 〕% (43)=〔 〕%
(44)110%=〔 〕 (45)300%=〔 〕 (46)%=〔 〕
(47)%=〔 〕 (48) =〔 〕%(49) =〔 〕 (50) =〔 〕%
二、化简比〔10×1分=10分〕
(51)36∶9 (52)80∶16 (53)7∶ (54) (55)∶ (56) (57)81∶18 (58) (59)∶25 (60)
三、解方程〔10×1分=10分〕
(61) (62) (63)
(64) (65) (66)
(67) (68) (69) (70)
四、计算〔30×1分=30分〕能简便的就简便
