There is no such number.
One decimal number between 3.66 and 3.75 is 3.7
There are an infinite number of fractions, and one decimal, that do. The decimal is 0.375 .
0.001
There is no decimal number immediately after. Given any decimal number greater than 1.25 it is always possible to find one between 1.25 and that number. And then one between 1.25 and thatnumber, and so on.
If the decimal number can be expressed as a fraction (with one whole number over another), then it is a rational decimal number. So 7/5 is a rational number, and remains as such even if expressed in decimal form (of 1.4).
One to one
If you mean make 3.5 into a number that is between 0 and 2 then: Move the decimal of the 3.5 over one place or times it by 10. 10 has 1 zero in it so you move the decimal point over 1 place.
There are infinitely many decimal number between the two given ones. 0.69 is one such.
a proper fraction or a decimal
BCD is a decimal number. BCD is one specific way to store decimal numbers in computer memory.
a long number that is represented in the exponant of 10 (ex. 363500000 = 810 ) but REMEMBER: the number to the power of ten has to be between 0 and 10 and if it is a decimal, it is one over the notation
A "rational number" is one that can be written as a fraction, with integers in the numerator and the denominator. When written as a decimal number, you'll get either a terminating decimal (e.g., 8 / 5 = 1.6), or a periodic decimal - one that repeats eventually, over and over again (e.g., 1 / 7 = 0.142857 142857 142857 ...).
