Question

The ratio of cubes to spheres in a geometry box is 4:7. If there are 16 cubes, then how many spheres are there?

Answer 1

28 spheres.

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
