There are infinite rational numbers between 2 and 3.Explanation:Let us write a few decimal numbers between 2 and 3: 2.01, 2.001, 2.0001,.., 2.4, 2.90 etc. Just change digits after the decimal point and this way we can write infinite decimal numbers between 2 and 3. And each decimal number can be expressed in the form of p/q(rational number)2.01 = 201/1002.001 = 2001/1000... 2.4 = 24/10 and so on.So there are infinitely many rational numbers b/w 2 and 3.
Nine (2.1 to 2.9)
Write both numbers as decimal numbers, then look for terminating decimals between the two.
There are no integers (or whole numbers) between two and three. The fraction exactly half way between is 2.5. There are also an infinite number of other decimal numbers spread throughout.
There are an infinite number of decimal values between any two numbers. 5.01, 5.1, 5.999999 are examples.
.65, .68, .72; any decimal between these two numbers
321 and 34.128. 84.321-34.128=50.193. The resulting decimal number is 50.193 which is between 50 and 52.
5/3+(3/2)-1/3
Fractions have a 'bar' in them - 2/3 Decimals have a decimal point - 1.45
Infinity, probably. Real numbers include both rational, irrational numbers, and zero. Therefore any decimal number is a real number, and it's impossible to count all the decimal numbers in between 1/2 and 3/4.
Not "number", but "numbers" - there are infinitely many. For a start, get a decimal approximation (on your calculator) for the square root of 2 and 3, then get some terminating decimals that are between those.
Unless the decimal contains all zeroes to the right of the decimal point (for example, 2.00), it is not an integer, a whole number, or a natural number. The integers are: (...-3, -2, -1, 0, 1, 2, 3, ...); whole numbers are: (0, 1, 2, 3, ...); and natural numbers are: (1, 2, 3, ...). If the decimal is a terminating decimal (e.g., 3.25) or a repeating decimal (e.g., 3.252525252525...), the number is a rational number. If it is a decimal that does not repeat after some number of digits (e.g., pi or sqrt(2)), the number is irrational.
