Step-by-step explanation:

0.29*10= 2.9

0.29/10= 0.029

29*10= 290

29/10= 2.9

2.9*100= 290

2.9/100= 0.029

2900000/1000= 2900

Answer:

Step-by-step explanation:

0.29*10=2.9(since it is multiplied by ten and there is one 0 in number 10 the decimal place will come 1 unit right making it 2.9)

29*10=290here first multiply 29 and 1 and add one 0 to it)

29÷10(since it is divided by ten there will be decimal one unit left of 9 i.e.2.9)

29*10000(first multiply 29 and 1 and since there are 4 0's add 4 zero to the product that will give u 240000 .adding 0 depends upon the question)

2900000÷1000(here u shold just cancel the certain number of 0 in noth munerator and denominator.since there are 3 0 in denominator cancel 3 0 from denominator and 3 0 from numerator.Then wu will have

2900/1

since the denominator is 1 u can simply write 2900.

Hope this helps u!!
