If u add 28 and 35 the answer will be 63. I multiply the 4(blue bikes) to 7 and it equals to 28, so there are 28 blue bikes

Answer:

See below in bold.

Step-by-step explanation:

1. x/8 = 15/24

Cross multiplying:

24x = 8*15

x = (8*15)/24

x = 5.

2. 5/6 = 35/x

5x = 6*35

5x = 210

x = 210/5

x = 42.

3.<em> </em>18/42

Divide top and bottom by 6:

18 / 6 / 42/6

= 3/7.

4. 15/75

Divide top and bottom by 15:

= 1/5.
