2.7+4.6=0 6-0.06= 10-4.56= 2.4×0.3=
1.4÷0.01= 0.51÷0.3= 5.6÷(3.74-3.73)= 14.09-7.54-6.46=
分析:根据小数的加、减、乘、除及四则混合运算的运算法则计算即可,其中最后一个算式可据结合律进行简算.
解答:解:
2.7+4.6=7.3 6-0.06=5.94 10-4.56=5.44 2.4×0.3=0.72
1.4÷0.01=140 0.51÷0.3=1.7 5.6÷(3.74-3.73)=560 14.09-7.54-6.46=0.09
故答案为:7.3,5.94,5.44,0.72,140,1.7,560,0.09.
点评:计算小数加减法要注意小数点对齐,完成小数乘除法时,要注意小数点位置的变化.
