《2025年新思维口算题卡五年级数学下册苏教版》

1. 根据等式的性质在$\bigcirc$里填运算符号，在$\square$里填数。
① $5x = 80$
$5x\div5 = 80\bigcirc\square$
② $x\div1.4 = 7$
$x\div1.4\bigcirc\square = 7\bigcirc\square$
③ $0.6x = 1.8$
$0.6x\bigcirc\square = 1.8\bigcirc\square$
④ $x\div0.2 = 1.8$
$x\div0.2\bigcirc\square = 1.8\bigcirc\square$

答案： 1. ①÷5 ②×1.4 ×1.4 ③÷0.6 ÷0.6 ④×0.2 ×0.2
