直接寫出得數(shù) 67+303=	50-10.91=	0.8×10=	3 14 × 7 12 =
4 5 ÷ 6 25 =	24×50%=	6÷ 3 4 =	7 8 ×7=
5.6÷0.7=	4 5 + 3 10 =	98×99≈	562÷80≈

Answer 1

分析：根據(jù)整數(shù)減法、小數(shù)乘除法、分?jǐn)?shù)乘除法和數(shù)的估算的計(jì)算方法進(jìn)行計(jì)算即可得到答案．

解答：解：

67+303=370	50-10.91=39.09	0.8×10=8	3 14 × 7 12 = 1 8
4 5 ÷ 6 25 =3 1 3	24×50%=12	6÷ 3 4 =8	7 8 ×7=6 1 8
5.6÷0.7=8	4 5 + 3 10 =1 1 10	98×99≈10000	562÷80≈7

點(diǎn)評(píng)：此題主要考查是整數(shù)加法、小數(shù)乘除法、分?jǐn)?shù)乘除法和數(shù)的估算的計(jì)算方法．
