The base.
By using long division.
Apart from using a calculator, specifically if you multiply a whole number by a power of 10:* To multiply a whole number by 10, add a zero to the whole number. * To multiply a whole number by 100, add two zeros to the whole number. * Etc.
There are no consecutive whole numbers that make 5.25 using simple arithmetical operations.
Rounding to the nearest whole number is just what it sounds like: using a whole number in place of a fraction because it's easier to say six dollars than $5.98. If the number is 1/2 or less, it will round down - for example, 8.2 rounds down to 8 because it's between 8 and 8 1/2. If the number is 1/2 or more, it will round up - e.g., 4 3/4 rounds to 5.
$2,000
If you have a decimal, it means you have a portion of a number, not a whole number. For example, if you have $2.10, you have two whole dollars, but the ten cents are only a portion of a dollar (and notice, they are a "decimal" -- .10).

In approximate terms, yes.
Since 3.75 cannot be expressed without using a decimal point or fraction bar, it is not an integer, and therefore is not a whole number and cannot be a whole number. However, it can be rounded up to 4, which is a whole number.
It means to find an amount in dollars - without cents - that is closer, to the specified value, than any other whole amount of dollars. For example: to round $2.60 to the nearest dollar, the answer is $3.00. The difference in this case is $0.40; if you choose any other whole number of dollars, the difference will be greater than that.
Oh, dude, 0.07 as a whole number is just 0. It's like if you had 7 cents and someone asked you how many dollars you have, you'd be like, "Uh, none." So yeah, 0.07 as a whole number is a big fat zero.
It is equivalent to multiplying by the cube of that number.
Multiply the whole number times the numerator. Divide the product by the denominator.
