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：根據(jù)小數(shù)的加、減、乘、除及四則混合運算的運算法則計算即可，其中最后一個算式可據(jù)結(jié)合律進行簡算．
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
故答案為：7.3，5.94，5.44，0.72，140，1.7，560，0.09．
點評：計算小數(shù)加減法要注意小數(shù)點對齊，完成小數(shù)乘除法時，要注意小數(shù)點位置的變化．
