First, write it out. 6.55 = 6\(\frac{55}{100}\).
We need to simplify. Let's start by dividing the numerator and denominator by compatible numbers. I'll use 5 to start.
55÷5 = 11. 100÷5 = 20.
You cannot simplify \(\frac{11}{20}\) further, as 11 is a prime number.
Therefore, 6.55 in a mixed number form is 6\(\frac{11}{20}\).
Hope that helped you.
