《2025年黄冈小状元同步计算天天练六年级数学下册人教版》

1. 估算下面各题。
$\frac{219 + 508}{200\ \ \ 500}\approx$ $\frac{705 - 29}{700\ \ \ \square}\approx$ $\frac{196\times61}{\square\ \ \ \square}\approx$ $\frac{631\div71}{\square\ \ \ \square}\approx$
$1099 - 485\approx$ $5.9\times2.2\approx$ $468 + 719\approx$ $19.6\div4.9\approx$

答案： 700@@30@@670@@200@@60@@12000@@630@@70@@9@@600@@12@@1200@@4

2. 估一估，在$\bigcirc$中填上“$＜$”或“$＞$”。
$\frac{3}{5}+\frac{4}{7}\bigcirc1$ $23.9\times9.9\bigcirc239$
$15.8\times0.9\bigcirc15.8$ $46\div1.01\bigcirc46$
$2.36\times5.1\bigcirc10$ $2.9\times4.9\bigcirc15$
$\frac{1}{3}\div0.5\bigcirc1$ $\frac{4}{7}\div0.5\bigcirc1$
$100 - 20.2 - 40.3\bigcirc40$ $100 - 19.8 - 59.7\bigcirc20$
$10 + 13 + 10 + 11 + 10\bigcirc50$ $2.7-\frac{2}{3}\bigcirc1.7$
$\frac{3}{4}\times\frac{17}{3}\bigcirc4$ $12-\frac{7}{3}\bigcirc10$

答案： ＞@@＜@@＜@@＜@@＞@@＜@@＜@@＞@@＜@@＞@@＞@@＞@@＞@@＜
