Are you just asking how to simplify them into those fractions? For the first one, divide the numerator and denominator by 20. Look for the greatest common denominator and divide the top and bottom by it. The second one has a gcd of 15, so divide both top and bottom by 15 to get 1/4
No after the = sign That's my answer. All the fractions on the left are the ones I have to simplify.
I just want to make sure I did it right and didn't make careless mistakes :]
All of your answers are correct.
