Question

Write the ratio as a fraction in lowest terms
1 1/2 to 3 1/3

Answer 1

9/20

Explanation:

To find this, we need to convert again. Use the fact that a b/c = (ac + b) / c, to get 3/2 over 10/3. Multiply by the LCM (least common multiple) which is what it sounds like. :P

So, if you skip count, the least common multiple is 6, so you multiply by 6 on both sides to get 9/20.
