1、二、把下面的假分数化成带分数或整数。3 7 37 42 54 9 34 15 2 4 16 14 53 9 34 7 三、填上合适的数。 ( ) 8 24 13 = = ( )( ) ( ) 5 = ( ) 9 5 ( ) ( ) ( ) 6cm = dm 80cm = dm 283dm3 = m3 12dm = m 58cm2 = dm2 786mL = L 四、用分数表示下面各式的商。 5 10 11 18 19 2 7 44 45 12 13 1 12 7 8 5 9 3 1 4 15 10 3 8 10 4 26 28 19 17 41 35 6 71 6 7 2 8 20 34 6
2、36 2 ( ) 1 61 3 = = ( ) 13 = ( ) 3 138cm = dm 95cm = dm 818dm3 = m3 33dm = m 32cm2 = dm2 404mL = L 13 1 28 8 9 11 16 17 6 7 4 8 10 7 2 11 8 47 3 17 7 5 9 7 9 47 20 19 29 45 17 5 43 7 5 2 8 15 17 4 43 4 ( ) 1 37 ( ) 6 55cm = dm 57cm = dm 123dm3 = m3 83dm = m 71cm2 = dm2 996mL = L 5 1 16 18 10 15 14 1
3、5 5 11 7 8 2 13 2 1 1 18 6 4 7 10 3 76 13 21 19 39 41 5 87 3 7 4 16 19 40 4 44 2 ( ) 1 15 19 = ( ) 10 195cm = dm 70cm = dm 620dm3 = m3 33dm = m 51cm2 = dm2 322mL = L 9 11 43 44 4 5 7 24 25 16 17 2 13 10 10 5 8 3 58 5 10 8 2 7 8 3 58 15 11 31 64 74 7 43 17 8 2 8 16 73 6 43 9 ( ) 1 5 7 = ( ) 6 72cm = dm 71cm = dm 835dm3 = m3 80dm = m 83cm2 = dm2 596mL = L 5 7 1 49 8 6 11 1 42 6 2 1 8 6 1 18 4 1 4 13 9 2 10 8 3 96
