综合套题十
40 ÷ 1000 =	15.2 × 100 =	7.22 × 1000 =
200 ÷ 25 =	19.3 + 18.9 =	25 ×4 =
4.6 ÷ 1000 =	630 - 80 =	9.4 - 2.8 =
55.2 + 86 =	38.26 - 9.9 =	389 +35 =
2、简便计算
6.94 - (2.62 + 1.94 )	32000 ÷ (32 × 125 )	( 25 + 200 ) × 4
969 + 969 × 99	8 × (26 × 125 )	555 + 746 + 145 + 802 + 154
3、四则运算与灵活运用
102 ÷ (2 × 3) + 338	9.8 + 8.9 - 7.31	793 × 998
0.52 - 3.31 + 3.48	(592 ÷ 8 + 846) × 5	[(31+86)×5-441]×4
9907 - 215 - 385 - 907	25 × 72 × 125	( 495 + 245 ) ÷ 5
