解答： 解：

2 7 × 5 8 = 5 14	1 8 ÷ 3 4 = 1 6	1.25×8=10	12.56÷6.28=2	0.22=0.04
4 5 - 1 3 = 7 15	3.14×5=15.7	3.14×40=125.6	75×10%=7.5	1 3 ÷3- 1 9 =0
4 7 × 7 12 = 1 3	5 8 ÷ 5 4 = 1 2	2.5×0.4=1	12.56÷3.14=4	0.82=0.64
2 3 - 1 3 = 1 3	3 5 ×5=3	3.14×100%=3.14	75÷10%=750

點(diǎn)評(píng)：完成此類題目要細(xì)心分析式中數(shù)據(jù)，然后快速準(zhǔn)確得出答案．
