几个0.1是3

30个0.1是3,100个0.1是10

3.4里面有34个0.1 有340个0.01.① 3.4=3+0.4, 3里面有30个0.1,0.4 里面有4个0.1,30+4=34,共有有34个0.1 ② 3.4里面有340个0.01.3.4=3+0.4, 3里面有300个0.01,0.4 里面有40个0.01,300+40=340,共有有340个0.01

3个0.1是(0.3);3*0.1=0.3

57个0.01是多少57*0.01=0.573里面有多少个0.1.3÷0.1=30

3个0.1是0.313个0.01是0.1333个千分之一是0.033

0.7

0.1*10=10.01*3=0.030.01*10=0.10.01*92=0.920.001*10=0.010.001*48=0.0480.001*837=0.837所以,10个0.1是1,3个0.1是0.3;10个0.01是0.1,92个0.01是0.92;10个0.001是0.01,48个0.001是 0.048,837个0.001是0.837.故答案为:1,0.3,0.1,0.92,0.01,0.048,0.837.

个0.1加上3个0.1是( 0.1*4 + 0.7 ) 0.1*3 = 0

3.5是三个1和五个0.1组成的

3.4里面有几个0.1 也就是求3.4由多少个0.1构成,也即是把3.4每份分0.1,可以分多少份,那么应该用到除法,所以3.4÷0.1=34 同理有3.4里面有几个0.01也是这个意思,把3.4每份分0.01可以分多少份,那么应该用到除法,所以3.4÷0.01=340
