一、直接写得数。
$540 + 260 = $
$540÷6 = $
$780÷39 = $
$0.36×10 = $
$7.99×100 = $
$540 + 260 = $
800
$256 - 99 = $157
$700×8 = $5600
$540÷6 = $
90
$3500÷5÷7 = $100
$25×32 = $800
$780÷39 = $
20
$15×40 = $600
$0÷72 = $0
$0.36×10 = $
3.6
$0.875÷10 = $0.0875
$16.5÷100 = $0.165
$7.99×100 = $
799
$5 - 3.6 = $1.4
$15.8 + 0.2 = $16
答案
800 157 5600 90 100 800 20 600 0 3.6 0.0875 0.165 799 1.4 16
二、用竖式计算并验算。
$1.59 - 0.347 = $
验算: 验算:
$1.59 - 0.347 = $
1.243
$0.96 + 0.681 = $1.641
验算: 验算:
答案
1.243 1.641
