The local mechanic worked on a total of 18 cars and trucks this week. If he worked on 13 cars, predict the ratio of cars to trucks that were worked on for the week.(1 point) Responses 5:18 ratio of 5 to 18 13:5 ratio of 13 to 5 5:13 ratio of 5 to 13 13:18

Answer 1

To find the ratio of cars to trucks, we first need to determine the number of trucks worked on.

The total number of vehicles (cars + trucks) is 18. The mechanic worked on 13 cars. Therefore, the number of trucks worked on can be calculated as:

\[ \text{Number of trucks} = \text{Total vehicles} - \text{Number of cars} = 18 - 13 = 5 \]

Now, the ratio of cars to trucks is:

\[ \text{Ratio of cars to trucks} = \frac{\text{Number of cars}}{\text{Number of trucks}} = \frac{13}{5} \]

This can be expressed as the ratio 13:5.

So, the correct response is:

13:5 ratio of 13 to 5.
