Answer by jim_thompson5910(35256)   (Show Source):
You can put this solution on YOUR website! Let x = the unknown number (ie the "given number")
40% of a given number is 8
40% of a given number is 8
0.4 * x = 8
0.4 x = 8
0.4x = 8
x = 8/0.4
x = 20
So the "given number" is 20
-------------------------------------------------------------------
Now take 15% of that given number:
20*0.15 = 3
So 15% of 20 is 3
=======================================================================
Answer:
15% of the given number is 3
