Of the cars in a used-car lot, 25 are the color gray. 13 of the gray cars are electrically powered vehicles. What fraction of the cars on the lot are both gray and electrically powered? Leave your answer in simplified fraction form.
Of all the cars, if 25 are grey, then the fraction of cars that are grey is $\frac{25}{25} = \boxed{1}$.
To find the fraction of cars on the lot that are both gray and electrically powered, we can divide the number of gray and electrically powered cars by the total number of cars on the lot.
Given that there are 25 gray cars, and 13 of them are electrically powered, we can say that the fraction of cars that are both gray and electrically powered is:
13/25
So, the fraction of cars on the lot that are both gray and electrically powered is 13/25.
To find the fraction of cars that are both gray and electrically powered, we need to divide the number of gray electric cars by the total number of cars on the lot.
First, we know that there are 25 gray cars. Out of these 25 gray cars, 13 of them are electrically powered.
So, the fraction of cars that are both gray and electrically powered is 13/25.
