Answer:

28 spheres.

Step-by-step explanation:

Ratio:

Ratio of cubes to spheres = 4 : 7

Number of cubes = 4x

Number of spheres = 7x

Given that number of cubes = 16

⇒ 4x = 16

Divide both sides by 4

     x = 16/4

     x = 4

Number of spheres = 7x

                                 = 7*4

                                 = 28
