Final answer:
To convert 0.85 to a fraction, write it as 85/100 and then simplify it by dividing both the numerator and denominator by 5, resulting in the simplest form, 17/20.
Step-by-step explanation:
To write the number 0.85 as a fraction in its simplest form, you first write it as a fraction with a denominator of 100. This is because 0.85 can be interpreted as 85 percent, and a percent is a fraction out of 100. So, you get:
0.85 = 85/100
Now you simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor (GCD), which is 5 in this case.
85 ÷ 5 = 17
100 ÷ 5 = 20
Therefore, in its simplest form, 0.85 as a fraction is 17/20.
To express the number 0.85 as a fraction in its simplest form, start by writing it as 85/100, considering the percent representation. Simplify the fraction by dividing both the numerator and denominator by their greatest common divisor (GCD), which is 5. This results in 17/20 as the simplified form of 0.85.
