Question

A toy plush weighed 1/5 of a pound. a flimsy box can hold 3 pounds. how many toy plushes could the box hold?

Answer 1

So how many 1/5 pounds can a box, that holds 3 pounds, hold?
total weight = 1/5 times the amount of toys
3 = 1/5 x
rewrite
3 = 1x /5
multiply both sides by 5
15 = 1x 
15 = x 

The flimsy box can hold 15 toy plushes.

Hope this helps
