In a certain town the ratio of the number of cars to that of taxis is 15:4. If there are 172 taxis in the town , find the number of cars there.

4 /8

To find the number of cars in the town, we can use the given ratio of 15 cars to 4 taxis.

Step 1: Let's assign variables for the unknown quantities. Let's call the number of cars x.

Step 2: Use the ratio to set up an equation. We know that the ratio of cars to taxis is 15:4. Therefore, we can write:

15/4 = x/172

Step 3: Solve the equation for x. We can cross-multiply to get rid of the fractions:

15 * 172 = 4 * x

2580 = 4x

Step 4: Divide both sides of the equation by 4 to isolate x:

x = 2580 / 4

x = 645

Therefore, there are 645 cars in the town.

645

the cars make up 15/19 of the total.

I suspect a typo.
