To convert a fraction to a decimal using bar notation, divide the numerator by the denominator. If the division results in a repeating decimal, you represent the repeating part with a bar over the digits that repeat. For example, the fraction ( \frac{1}{3} ) converts to the decimal 0.333..., which can be expressed as ( 0.\overline{3} ) to indicate that the digit '3' repeats indefinitely.

It is a terminating decimal fraction.
-- A fraction is just a shorthand way of writing a division problem. When you see a fraction, it means (the top number) divided by (the bottom number). -- Take the fraction. Set up the division problem, and do the division. -- The answer to the division is the decimal form of the fraction. -- Take the decimal form. Move the decimal point in it two places to the right. Now you have the percent that's equal to the fraction.

how can you use expanded notation to find an equivalent decimal
you can find it by putting it in expanded from
Any kind of fraction becomes decimal notation if you divide the denominator into the numerator. Any decimal notation becomes a percent if you multiply it by 100.

42.3 is already in its decimal notation but it can be written as 423/10 as an improper fraction.
There isn't one. In fractional notation it is 151515/1, in decimal notation it is 151515.00

You do it be long division.
To change a fraction to a decimal: Perform the indicated division. To change a fraction to a percent: Perform the indicated division. Then multiply the quotient by 100.
