Respuesta :
Let the circle represent 100%, and let us divide it into fifths, that is, into five equal parts -- into 20's. Each 20% is a fifth of the circle. Two fifths of the circle -- of 100% -- is 40% Three fifths is 60%. Four fifths is 80%.
its 16 because 4/5 you have to start withe demonitrator with five and muptily by 4 and you will get 20 on the bottom and 16 on the top
