9/10 - 1/10 = 8/10. 
When subtracting fractions with like denominators, you really only need to worry about the numerators. 9 - 1 = 8, so the answer is 8/10.
As we can see, both 8 and 10 are divisible by 2, so we can simplify the answer a bit.
8 / 2 = 4
10/ 2 = 5
The final simplified answer is 4/5.
Hope that helped =)

Since the denominators are the same, we can just combine the numerators together.

\(\frac{9-1}{10}\)

Now, we just have to subtract the numerators to get our new fraction.

\(\frac{8}{10}\)

But, our fraction is not in simplest form yet. We can find the GCF of 8 and 10 and then divide the numerator and denominator by it.

The GCF = 2, so now we can divide.

\(8 \div 2 = 4 \\ 10 \div 2 = 5 \\ \\\)

Gather the new numerator and denominator to get our simplified fraction.

The final result is: 4/5 or 0.8
