The decimal 0.85 can be converted to the fraction 85100, by definition of a decimal. This fraction 85100, however, is not in simplest form. The fraction can be simplified to 1720, as both the numerator (top) and denominator (bottom) of the fraction are divisible by 5.
Therefore, your answer is 1720

The first step we can take is to put 85 over 100 because .85 is the same thing as 85 hundreths (we can remember this by noting that there are two decimal places in .85, or the numerator, meaning that there are two zeros in the denominator), which is the same thing as 85100
.85=85100
We can simplify this by dividing the numerator and denominator by the greatest common factor (in this case, 5).
85100÷55=1720
17 is a prime number, so theres

So 0.85 is the same as 810+5100
Multiply by 1 and you do not change the value. However 1 comes in many forms. So write as:
=[810×1]+5100
=[810×1010]+5100
=[80100]+5100
=80+5100
=85100
But 5 will divide exactly into both 85 and 100
When dividing or multiplying what you do the top of a fraction you also do to the bottom. In doing so we 'simplify' to an 'equivalent' fraction
85÷5100÷5=1720
Where the symbol  means 'equivalent to'
