2:10 is equivalent. To get the answer you multiply 1 & 2 by their LCM (least common multiple) , which is 2, and that's how you get the answer, and to check to see if it's right just divide by 2 but if you know multiples of 1 and 5 then you could've easily looked at the answer choices to find your answer.

hopefully this helps
