Question

4/25 of the purchases were stuffed animals. 10/21 of them were bears. What fraction of the purchases were stuffed bears?

Answer 1

let's name all the purchases "x"

so
`(4)/(25)`of them were stuffed animals, and out of that
`(10)/(21)` were bears.

to get the results we have to multiply the fraction of bears by the fraction of the stuff animals:


`(4)/(25)*(10)/(21)`.

and now we simplify:

`(4*2)/(5*21)`=
`(8)/(105)`

and this is the answer!
