Ok, so we know that the radius of Sphere A is 24 cm, and we know that the diameter of Sphere B is 42 cm. To find the radius of Sphere B, all we need to do is divide the diameter by two. The radius of Sphere B is 21 cm. 24 times what factor is 21? Well,
24* (21)/(24) is equal to 21. All we need to do now is simplify it. Divide the numerator and denominator by 3, and we get
(7)/(8)
