There are three different situations, corresponding to the three types of decimal numbers: terminating, repeating and those which are neither terminating nor repeating.
Terminating: If the decimal number has d digits after the decimal point, then rename it as a fraction whose numerator is the decimal number without the decimal point, and the denominator is 10^d or 1 followed by d zeros.
For example, 34.56
d = 2 so the denominator is 100.
and the fraction is 3456/100.
Repeating: Until you become expert at this I suggest you do this in two stages (using c and d separately). Suppose there are c digits after the decimal place where the digits are non-repeating, and then you get a repeating pattern of a string of d digits. Then the numerator is the old original string including one lot of the repeated digits minus the original string with none of the repeating digits. The denominator is 10^c*(10^d - 1), which is a string of d 9s followed by c 0s.
For example
123.26159159… There are 2 digits, "26", after the decimal point before the repeats kick in so c = 2, and the repeating string "159" is 3 digits long so d = 3.
So the numerator is 12326159 – 12326 = 12313833
and the denominator is 99900
Therefore the fraction is 12313833/99900.
Non-terminating and non-repeating: There is no way to get a proper fraction since, by definition, this is an irrational number. The best that you can do is to round it to a suitable number of digits and then treat that answer as a terminating decimal.
In all cases, you should check to see if the fraction can be simplified.
turn both fractions into decimals and then multiply!
Change the decimal into a fraction or the easier way is to turn the fration into a decimal, then multiply.
You should be familiar with long division involving decimals
Restate the question: If you can write a fraction as a decimal, can you write a decimal as a fraction?Yes.
155 is an integer not a fraction.

do 1 divided by 2, it always works with any fraction when converting them to decimals. the answer is 0.5.

If you convert repeating decimals into a fraction, you see that the repeating decimals are rational.
decimals
you can change the fraction into a decimal or vice-versa
first you must turn the decimal into a fraction. then simplify it. Okay so i put 45 over 100
They are related because you can comvert decimals into fractions,and fractions into decimals.
