Destiny designs necklaces.
She uses between 15 and 20 yellow and blue beads in a ratio of 4 yellow beads to 5 blue beads.

Drag the beads into the container to meet these requirements.

CLEAR CHECK

Step-by-step explanation:

Well, the ratio of yellow beads to blue beads is 4:5. The best way I think is to guess and check multiplying the ratio by integers. You need between 15 and 20.

4 : 5 ( = 9 too little )

8 : 10 ( = 18 just right)

12 : 15 ( = 27 too much)

So per necklace, 8 yellow beads and 10 blue beads would be needed. 

I hope this helps :-)

won't that be plagrisim thought?
