Answer:
19/20-11/20 is 8/20, or 2/5 in simplest form.
Explanation:
These are both like terms already, so you can just subtract: 19-11=8
Then, since they both have the same denominator, you will just take 8 and put it over 20, like so: 8/20
However, this fraction can be simplified.
The GCF of these two numbers is 4. So, 8÷4=2 and 20÷4=5
So, 2 is the numerator and 5 is the denominator, meaning that you would have 2/5 as your answer.
