Hi there!
The word "of" is the same thing as a multiplication sign.
1)
20% = 0.2
0.2 × 20 = 4
2)
? × 30 = 15
divide each side of the equation by 30
? = 0.5
0.5 = 50%
3)
50% = 0.5
0.5 × ? = 50
divide each side of the equation by 0.5
? = 100
There you go! I really hope this helped, if there's anything just let me know! :)
