Proper. Proper fractions are when the numerator (top number) is smaller then the denominator (bottom number), improper fractions being the opposite- think of 5/3, 8/5, etc. In the fractions 5/9 and 10/20 both numerators are smaller then the denominator, making them proper fractions. If there’s an option to simplify the numbers on the question; 5/9 would stay the same and 10/20 would turn into 1/2. Hope this helps!
