How do I solve this?

Question

dolls = 45

footballs = 105

small cars = 75

 

These toys will be placed on shelves so that each shelf has the same number of each type of toy.  How many shelves are needed for each type of toys so that it has the greatest number of toys?

Answer 1

Dawn, what is the GCF of 45, 75 and 105?

 

45 = 3 x 3 x 5

75 = 3 × 5 × 5

105 = 3 × 5 × 7

 

Since we need the fewest number of shelves, we need 3 shelves, the smallest common factor.

 

Hope this helps!
