Answer:
I believe they are if they are looking at each as an individual pair.
Step-by-step explanation:
5:1 and 15:3 are both 5 (think of them as fractions [tex]\frac{5}{1}[/tex] and [tex]\frac{15}{3}[/tex]. simplify to 5
the same is true for 10:2 and 25:5 ([tex]\frac{10}{2}[/tex] and [tex]\frac{25}{5}[/tex] both simplify to 5)
the last one is 198:1287 and 2:13 ( [tex]\frac{198}{1287}[/tex] and [tex]\frac{2}{13}[/tex] both simplify to .154)
