五年级数学离型计算题和300题答案最好有个过程。

0.45×2.5=1.125 0.8×1.25=1 0.3×3.6=1.08 0.3×0.3=0.09 10×0.07= 0.7 0.92×0.4= 0.368 0.2×0.26=0.052 0.14×4= 0.56 0.02×0.1= 0.002 1.2×0.3= 0.362.5×0.4= 1 2.4×5= 12 0.22×4= 0.88 3.25×0=0

0.9-0.52= 0.38 3.99×1=3.99 0×3.52= 0 12.5×8=100

8÷10 = 0.8 10-1.8-7.2= 1 0.43+3.57= 4 2.5×4×12=144

0.9×0.8 = 0.72 7.5x-3x = 4.5x a+3a+7a = = 11a 1.05×100 = 105 1÷0.5 = 2 0.96÷3 = 0.32

0.6×0.8 = 0.48 3×0.9= 2.7 2.5×0.4= 1

0.16×5 = 0.8 1.78+2.2 = 3.98 1.2×0.5-0.4 = 0.2 0.7÷0.01 = 70 2.5×0.4 = 1 12-3.9= 8.1 1.25×8÷1.25 = 8 6.6÷0.66 = 10 5.37×0+4.63 =4.63 3.9+2.03= 5.93

7.2+2.8=10 1.4×5= 7

2、带垂直计算
