The ratio of blue to red cars in a parking lot is 4/7. If there are 168 blue cars about how many red cars are there?
4/7=x/168
672=7x
x=96
The blue cars are the 4, so the red cars > blue cars.
7/4 = x/168
x = 294
To find the number of red cars in the parking lot given the ratio of blue to red cars and the number of blue cars, you can set up a proportion.
The ratio of blue to red cars is given as 4/7. Let x represent the number of red cars.
Then, you can set up the proportion:
blue cars / red cars = given blue ratio / given red ratio
168 / x = 4 / 7
To solve for x, you can cross multiply:
4x = 168 * 7
4x = 1176
Dividing both sides by 4:
x = 1176 / 4
x = 294
Therefore, there are approximately 294 red cars in the parking lot.
