直接寫出得數(shù)． 5 16 × 8 15 =	17 2 × 6 17 =	5 8 × 7 10 =	5 6 × 30 50 =
99 66 × 22 33 =	8 9 ÷ 4 9 =	13 15 ÷13=	1 10 ÷ 1 100 =
9 25 ÷ 3 5 =	3 4 ÷ 3 5 =

Answer 1

分析：根據(jù)分?jǐn)?shù)乘、除法的計(jì)算的方法進(jìn)行計(jì)算，能約分的要先約分，再計(jì)算．

解答：解：

5 16 × 8 15 = 1 6	17 2 × 6 17 =3	5 8 × 7 10 = 7 16	5 6 × 30 50 = 1 2
99 66 × 22 33 =1	8 9 ÷ 4 9 =2	13 15 ÷13= 1 15	1 10 ÷ 1 100 =10
9 25 ÷ 3 5 = 3 5	3 4 ÷ 3 5 = 5 4

點(diǎn)評(píng)：計(jì)算時(shí)，要靈活運(yùn)用所學(xué)的知識(shí)，快速準(zhǔn)確的進(jìn)行計(jì)算．
