Answer 1

分析：本題根據(jù)小數(shù)、分?jǐn)?shù)的加法，減法，乘法，除法的運(yùn)算法則計算即可．

解答：解：

1.02-0.43=0.59	1.25×8=10	（0.18+1 9 10 ）÷9= 52 225	7 5 8 -2 3 8 =5 1 4	6.5×4× 1 5 =5.2	（ 3 8 + 4 8 ）×4=3.5
1 7 10 - 1 5 - 4 5 = 7 10	6.3×10%=0.63	3.75-2- 3 4 =1	5 9 - 5 9 ÷5= 4 9	4 4 5 -（3.8+ 4 9 ）= 5 9	1 1 2 -1 1 2 ÷3=1
（ 5 7 + 4 5 ）×35=53	3×9+3=30	5.38-（2.38+1.8）=1.2	5-1 2 5 -1.6=2	14× 7 8 × 1 7 = 7 4	4.4÷1 1 10 =4
1.25× 4 25 ×8=1.6	7.2÷8×4=3.6	5 1 2 - 1 5 =5.3	10.8-3.9-4.1=2.8	2.5- 1 4 +1 1 5 =3.45	1 1 5 + 5 6 + 4 5 =2 5 6

點(diǎn)評：完成本題要細(xì)心分析式中數(shù)據(jù)，能簡便計算的要簡便計算．
