**Minxia counted 40 green cars and 20 silver cars in the parking lot.**

If the number of green cars stays the same, how many more silver card would need to be added so the ratio of green cars to silver cars is 1 to 3?

**Answer**

What I did is I multiply 40 by 3 because 40 is 1/3 and I have to find the answer for 3/3 (Confusing, sorry I don't know how to explain it correctly).

I got 120, subtract 20 from 120 beacause ther is 20 silver cards.

The answer is 100
