3.先探索下面每组算式的规律,写出答案,再用计算器进行验算。(6%)(每小题0.5分)
(1)( 4 - 4 )÷ 36 = (2)( 6 - 6 )÷ 54 =
( 44- 8 )÷ 36 = ( 66 - 12 )÷ 54 =
( 444 - 12 )÷ 36 = ( 666 - 18 )÷ 54 =
( 4444 - 16 )÷ 36 = ( 6666 - 24 )÷ 54 =
( 44444 - 20 )÷ 36 = ( 66666 - 30 )÷ 54 =
( 444444 - 24 )÷ 36 = ( 666666 - 36 )÷ 54 =
三、计算。(53%)
1.直接写出得数。(12%)(每题1分)
24 ÷ 2 = 15 × 40 = 20 × 10 = 900 ÷ 9 =
30 × 31 = 0 ÷ 10 = 600 × 6 = 350 ÷ 7 =
210 × 4 = 690 ÷ 3 = 300 ÷ 6 = 50 × 80 =
2.列竖式计算,打“*”的题目要写出验算过程。(19%)(验算每题5分,其余每题3分)
29 × 38 = 648 ÷ 23 = 53 × 109 =
*7900 ÷35 = *76 × 450 =
3.用递等式计算。(16%)(每题4分)
64 ×46 + 54 780 ÷ 52 × 18
1652 ÷ ( 309 - 281 ) 105 × 25 - 1050 ÷ 25
