First you have to figure out the GCF (Greatest Common Factor) of 8 and 10. When you figure that out, the GCF is 2. So then, you would divide 2 by 8 and 10, then you should get the answer which is 4/5.
Well not all because ratios is basically the meaning of fractions so every time you have a problem always cross out the word ratios and put fractions because that will help you and then you tell us is equivalent to your answer such as 8/10 as a ratio and 1/9 as a ratio then you would have to put them across and tell them from each
