20% more than 15 of anything is 18 of the same thing.
1/5 = 20% so 15% < 20%
Well, 20 x .15 = 3, so 20 + 3 = 23
yes
60%.
15 = 1500% 20 = 2000%

No. Humankind would die out if more than 30% below the age of 20 died - of any cause.
1,600 + 20% = 1,920
225 + 20% = 270
150% more than 20= 20 + (150%* 20)= 20 + (1.5 * 20)= 20 + 30= 50
15% of 20 = 3
