Answer: 26
Step-by-step explanation:
10 : 3 means for every 3 songs he kept, he deleted 10
He deleted 20
10 * 2 = 20
3 * 2 = 6
He deleted 20 songs, and kept 6.
So, he had 26 songs on his MP3 player.
20 + 6 = 26
The mistake is in Step 1. The solver should have also squared 
when squaring the other side of the equation.
<h3>Correctly solving</h3>
3/4 of the bat blood was used = 18/24 most Ethel
2/3 of the knotgrass was used= 16/24 more Locasta
1/2 of the moonstone was used=12/24 less Circe
3/8 of the unicorn hair was used=9/24 least Glinda
Circe used the moonstone
