I'm wondering, because i'm doing this: 30% of 360m
I already know for example: 6%of $20 = 6/100 x 20/1
but when i'm doing: 30% of 360m = 30/100 x 360/1 (is that right? were mean't to be simplifying i think)
But when i multiply 30 by 360 i get: 10'800
How would i lay out my question! Because i'v converted the percentage and quantity to fraction.
Multiplyed and simplifyed (i hope)
And another one i'm puzzling over is: 75% of $1240
