Question

coloque as fraçoes em ordem decrescente:2 1/4,11/5,2
me ajudem por favor

Answer 1

21/4, 11/5, 2
MMC de 4, 5, 1 = 4*5*1 = 20
I) 21/4 => ([20/4] * 21)/20 = [5 * 21]/20 = 105/20
II) 11/5 => ([20/5] * 11)/20 = [4 * 11]/20 = 44/20
III) 2 => ([20/1] * 2)/20 = [20 * 2]/20 = 40/20

40/20 < 44/20 < 105/20 Ou 2 < 11/5 < 21/4
