1、二、把下面的假分数化成带分数或整数。20 7 17 34 38 7 42 17 5 2 8 17 37 6 42 8 三、填上合适的数。 ( ) 1 1110 13 = = ( )( ) ( ) 19 = ( ) 3 19 ( ) ( ) ( ) 7cm = dm 13cm = dm 708dm3 = m3 43dm = m 48cm2 = dm2 631mL = L 四、用分数表示下面各式的商。2 13 41 42 6 7 5 19 6 7 12 13 3 16 10 10 4 18 6 96 4 18 9 5 8 8 7 97 7 13 23 26 75 7 63 8 7 2 8 13 7
2、4 7 31 2 ( ) 6 131 ( ) 7 192cm = dm 13cm = dm 404dm3 = m3 25dm = m 45cm2 = dm2 804mL = L 3 1 30 12 11 13 1 37 12 3 13 10 10 1 12 3 53 2 15 7 4 8 6 3 54 19 7 23 40 53 4 77 13 9 4 16 10 52 4 39 6 ( ) 1 83 11 = ( ) 2 113cm = dm 57cm = dm 229dm3 = m3 64dm = m 24cm2 = dm2 366mL = L 8 19 5 6 18 19 40 16 1
