Question

Помогите.
5% некоторого числа равны 11. Найдите 15%, 20%, 35%, 50%, 100% этого числа,

Answer 1

11 - 5 ; x - 100
x = (11 • 100)/5
x = 220

220 - 100 ; x - 15
x = ( 220 • 15)/100
x = 33

220 - 100 ; x - 20
x = (220 • 20)/100
x = 44

220 - 100 ; x - 35
x = ( 220 • 35)/100
x = 77

220 - 100 ; x - 50
x = (220 • 50)/100
x = 110

220 - 100 ; x - 100
x = (220 • 100)/100
x = 220
