Question

The ratio of cars to bikes is 8:7. If there are a total of 21 bikes, find the number of cars.​

Answer 1

Answer:

Numbers of cars = 24 .

Step-by-step explanation:

Ratio of cars to bikes is 8:7 .

Total 21 bikes .

Bikes = 7x

7x= 21

=> x= 3

Cars = 8x= 8*3 =24 .

Answer 2

Here the ratio of cars to bikes is given to be 8:7

Let the number of cars and bikes be 8x and 7x respectively

Also, the number of total bikes is 21

so, 7x = 21

      x = 21/7

      x = 3

Now, we have to find the total number of cars

total number of cars = 8x

                                = 8 × 3

                                 = 24

Hence, the total number of cars will be 24
