write each fraction or mixed number as a decimal 3 over 4?
Everywhere. Each and every point on a number line is a fraction and also a decimal.
A decimal number is one in which the place value of each digit is ten times the place value of the digit to its right. (... , thousands, hundreds, tens, units, tenths, hundredths, ... ) A decimal point is used to separate the units from the tenths. If a number in decimal form has non-zero digits after the decimal point then it is a decimal fraction. [There is one esoteric exception: if the decimal point is followed by an infinite string of 9s, then it is not a decimal fraction.] Thus 37.6 is a decimal fraction 0.6 is a decimal fraction 0.00000063 is a decimal fraction 37 is not a decimal fraction. 37.0 is not a decimal fraction. 37.999... recurring is no a decimal fraction [it is in fact = 38].
When you get a repeating decimal when dividing, it means that the decimal representation of the quotient has a repeating pattern of digits. This occurs when the divisor (the number you're dividing by) is not a factor of 10, leading to a situation where the division process does not result in a clean, terminating decimal. The repeating decimal is a way to represent the fraction that results from the division in a concise form.

Every fraction is an equivalent fraction: each fraction in decimal form has an equivalent rational fraction as well as an equivalent percentage fraction.

A fraction is a division problem, such as one divided by two, which equals a half. This can be written as 1/2. In decimal form it is .5 since five tenths is a half. If you have a mixed number, such as 17 and 2/3, that can be written in decimal form as 17.67 (but note that this is only an approximation since 2/3 gives an infinitely long decimal expansion, .6666666666666666666666666 etc.).
1/17 contains each of the ten digits.
Every number with a finite number of digits can be made into a fraction. Start by writing your decimal number in the numerator, divided by 1 in the denominator (since dividing by 1 doesn't change the value of any number). Then, each time you move the decimal place to the right, add one "0" to the denominator. In this case, since there are two decimal places, we add two zeros, and the fraction is 863/100.
