一、直接写出得数。
1.24 + 3.76 = 0.36 × 10 = 2.8 - 1.5 = 1.25 × 0.08 =
4.5 × 20 = 0.23 × 7 = 60.3 - 17.3 = 2.6 × 0.2 =
2 - 1.35 = 28 ÷ 100 = 2 × 0.47 = 5 × 0.68 =
2.7 + 4 = 9.3 - 4.5 = 0.86 + 1.34 = 0.7 ÷ 100 =
1.24 + 3.76 = 0.36 × 10 = 2.8 - 1.5 = 1.25 × 0.08 =

答案:
三、30 9 123 90.2 5.454 72
四、根据835 × 24 = 20040,在( )里填上适当的数。
( ) × ( ) = 2.004 ( ) × ( ) = 200.4
( ) × ( ) = 2.004 ( ) × ( ) = 200.4
( ) × ( ) = 2.004 ( ) × ( ) = 200.4
( ) × ( ) = 2.004 ( ) × ( ) = 200.4
( ) × ( ) = 2.004 ( ) × ( ) = 200.4
( ) × ( ) = 2.004 ( ) × ( ) = 200.4
( ) × ( ) = 2.004 ( ) × ( ) = 200.4
( ) × ( ) = 2.004 ( ) × ( ) = 200.4
答案:
四、8.35×0.24 835×0.24 0.835×2.4 8.35×24 83.5×0.024 0.835×240 0.0835×24 8350×0.024(答案不唯一)
