Yes.

Yes, because it can be located on a number line.

In relation to what? In a general sense they are the rules that govern their usage in mathematics and also define their properties. Huurrrmmppfff. I think.

It is: 300,000,000

1.4 = one and four tenths.

Counting is finding out how many discrete objects are in a given collection by usually naming each of the natural numbers one after the other going up.

One terabecquerels, or 1000000000000 becquerel - depending on what you mean by "long hand".

250,000

140,000,000

If you were writing this amount on a personal check, on the line below the payee you would write:
Three-Thousand, Seventy-Eight Dollars and 00 cents.

To express this number in word form it would be: Three-thousand, Seventy-Eight

Let the numbers be x+4.27 and x:-

If: (x+4.27*x = 39.465

Then: x^2 +4.27x -39.465 = 0

Using the quadratic equation formula gives x a positive value of 4.5

Therefore the numbers are: 8.77 and 4.5

Check: 8.77*4.5 = 39.465

Placing a question mark at the end of a phrase does not make it a sensible question. Try to use a whole sentence to describe what it is that you want answered.

You need to rewrite so we can understand

It is 127 in decimal numbers.

It would be 20,000 rounded to the nearest hundred and not 19,900

6007000

7 is a whole number.

It is 1 + 0.08 + 0.001

Fifty-six hundredths

1,145,237 = 1.145237 x 10^6

53, 59, 61, 67, 71, 73.

1. Make it as simple as possible

2. Find your x, or whatever variable you are using

3. Be careful when graphing, the curves and axes intercepts should be accurate

It is a representation of the number in a form such that the place value of the digit to the immediate left of the decimal point is ones (or units) and the place value of each digit is ten times that of the digit to its right.

It is 5.4*10^1.

Real numbers are all numbers that do not have a complex component (i = sqrt(-1)). They are used for everything in the real world from totalling up a grocery bill to calculating the area of a circle.
