4.13+2.24= 5.16+7.89= 4.17+2.53= 5.07-0.98= 5.67-0.73= 13.18+5.27= 小数加减法的训练：（B） 2.小数数位不同的加减法 26.8+3.02= 6.07-4.993= 3.7+2.36= 15.4+2.97= 10.2-8.75= 12.7+6.58= 7.3-2.25= 3.8+3.54= 3.05-2.9= 3.1-2.07= 7.81-3.735= 12.16+5.347= 0.4-0.125= 18.7+3.96=
9.6+4.78= 62.1-17.07= 5.67-0.845= 0.506-0.19= 11.04-7.3= 1.4-0.405= 1.4-0.405= 3.906+0.66= 75.6-3.55= 10.1-0.55= 5.94+10.7= 12.03+0.875= 37.8+3.02= 0.704-0.25= 小数加减法的训练：（B） 3.整数与小数的加减法 10+10.1= 27+8.03=
