1.5×0.2=3.8×4=2.5×4=20×0.5=4.8÷1.6=1.5×5=10－4.5=

0.39÷3=7.2÷4=6÷5=

二、竖式计算

45.2－33.5=38－33.4=8.25+1.55=7.3－2.25=10－2.45=3.7+2.36=10.2－8.75=

15.4+2.97=5.94+10.7=11.65－7.39=10－3.14=11.7+40.3=3.15－2=8－7.23=

3.8+3.54=3.05－2.9=85－34.7=0.7×7.8=1.3×0.25=1.44×3.98=1.44×3.98=

1.36×0.8=0.78×0.04=4.8×0.25=4.8×1.2=0.32×0.8=0.32×1.2=9.8×0.5=

9.8×1.3=654×0.9=2.42×1.1=3.14×1.5=2.6×0.8=2.15×2.1=2.1×60=

0.12×50=2.6×0.5=1.2×60=2.13×4=4.8×0.3=1.3×2.2=9.6×0.8=3.25×1.8=
