 
 <prompt> ```One laboratory get 22 beakers wey get liquid inside for fume hood, and 8 of the beakers get copper ions inside. If dem add three drops of solution inside, the liquid for inside one beaker go turn blue if copper ions dey inside. If dem dey test the beakers one by one for copper ions and dem use 45 drops before dem find all the 8 beakers wey get copper ions, how many beakers wey no get copper ions dem test?``` <response>: ```Dey test 45 / 3 = 15 beakers to find all the beakers wey get copper ions.
So, dem test 15 - 8 = 7 beakers wey no get copper ions.

The answer go be 7.```
