$1.05×0.6=$
$3.3÷0.11=$
$4.5×0.4=$
$1.72+0.4=$
$0.56÷0.8=$
$4×0.25=$
$0.83+1.17=$
$1.32×0.5=$
$1.05×0.6=$
0.63
$1.05÷0.7=$1.5
$4.2×30=$126
$3.3÷0.11=$
30
$1.08×0.8=$0.864
$8.5÷0.17=$50
$4.5×0.4=$
1.8
$0.9-0.46=$0.44
$2.7+5=$7.7
$1.72+0.4=$
2.12
$0.46÷4.6=$0.1
$2.56-0.37=$2.19
$0.56÷0.8=$
0.7
$0.125÷0.25=$0.5
$3.4×0.2=$0.68
$4×0.25=$
1
$0.55×4=$2.2
$6+3.9=$9.9
$0.83+1.17=$
2
$0.83-0.62=$0.21
$3.8+0.03=$3.83
$1.32×0.5=$
0.66
$3.2×0.9=$2.88
$4.8÷0.06=$80
答案
0.63 1.5 126 30 0.864 50 1.8 0.44 7.7 2.12 0.1 2.19 0.7 0.5 0.68 1 2.2 9.9 2 0.21 3.83 0.66 2.88 80
二、用竖式计算。
$50.6-24.45$ $3.7×0.66$ $1.43÷0.11$
$4.77+16.28$ $4.425÷2.5$ $1.4×2.95$
$50.6-24.45$ $3.7×0.66$ $1.43÷0.11$
$4.77+16.28$ $4.425÷2.5$ $1.4×2.95$
答案
26.15 2.442 13 21.05 1.77 4.13
