Answer 1

分析：根据整数、小数和分数四则运算的计算法则进行计算即可．

解答：解：

636-198=438	3.6÷0.36=10	7÷14=0.5	1- 2 5 + 3 5 =1 1 5
1+ 1 4 =1 1 4	1 1 4 × 1 4 = 5 16	1 4 ÷ 1 4 =1	1- 1 4 = 3 4
37×5=185	9-0.9=8.1	（ 1 4 + 1 3 ）×24=14	72×0.4=28.8
72÷0.4=180	24× 3 4 =18	0.2- 1 5 =0	1+ 3 2 × 2 3 =2
25×24=600	4.2÷0.2=21	12-0.2=11.8	1.25×8=10．

点评：此题考查了整数、小数和分数四则运算的计算法则的运用．
