The answer is 5 39/100
5.39 as a fraction is 539/100
To make that a mixed number you need to find out how many times the denominator goes into the numerator (100 goes into 539 5 times) so your whole number is 5 and you're left with 39/100 as the fraction, which can't be simplified any more.
Answer: Required expression : 
Smallest number = 27
Step-by-step explanation:
Let the three consecutive number be n-1 , n , n+1 .
Since , the sum of three consecutive numbers is 84.

i.e. 27 , 28 , 29.
Hence, the smallest number is 27.
