Question

直接寫出得數(shù)

1 6 ×2=	15× 4 3 =	3 7 × 1 3 =	5 8 × 8 13 =
3 5 - 1 5 =	7 9 × 4 7 =	5 13 ×13=	1 2 ×0× 22 23 =

Answer 1

考點：分數(shù)乘法

專題：運算順序及法則

分析：根據(jù)分數(shù)乘法的計算方法：能約分的先約分進行求解．

解答： 解：

1 6 ×2=3	15× 4 3 =20	3 7 × 1 3 = 1 7	5 8 × 8 13 = 5 13
3 5 - 1 5 = 2 5	7 9 × 4 7 = 4 9	5 13 ×13=5	1 2 ×0× 22 23 =0

點評：本題考查了分數(shù)乘法的計算方法，掌握計算法則是解題關(guān)鍵．
