18% = 18/100 so
18/100 of 400 = 18/100 * 400 = 72

If 18% = 18/100, and 100*4 = 400...
then 18*4 = 72
Try it.... 0.18*400 = 72

The answer is 72!
The sum i done was: 400 divided by 100, times by 18!
I took the quantity (400) and devided by the maximum possible percentage (100 coz percentage is always out of 100) and then this gave me 1%, I then times by 18 2 get 18%!
gud luk!

All you need to do is multiply 400 x 0.18 (which is 18/100 or 18%). and you get 72.

18%x400
18/100x400
18x4
72
because percent means per a hundred
so 18%of 400
is 18 per a hundred times 400
