Explanation:
when in doubt in a % problem, always find 100% and 1%. everything else can be calculated out of this.
100% = 400
1% = 100%/100 = 400/100 = 4
how many % is 240 ?
well, as many % as times that 1% fits into 240 :
240/4 = 60%
Answer:
n = 60.
60% of 400 is 240, because:
240/400 = 0.6 = 60%
0.60 * 400 = 240
