The ratio of trucks to cars is 7 to 8. if there are a total
of 21 trucks, how many cars are there?

We can write the ration in the question as 7:8.

If the new value of trucks is 21, we can divide by the original to find how many times it grew by.

21 / 7 = 3

Now, we can multiply this to how the original amount of cars to find the new amount.

8 * 3 = 24

Now, write the new ratio.

21:24

Hope This Helped! Good Luck!
