Question

Qual a representação decimal de 33/4 , 9/5 , 1/2 , 11/8 e 3/20 ?

Answer 1

33/4 = 8,25
9/5 = 1,8
1/2 = 0,50
11/8 = 1,375
3/2 = 0,15

Answer 2

Olá,

11/8 = (8+3)/8 = 8/8 + 3/8 = 1 + 0,375 = 1,375

9/5 = (5+4)/5 = 5/5 + 4/5 = 1 + 0,8 = 1,8

33/4 = (32+1)/4 = 32/4 + 1/4 = 8 + 0,25 = 8,25

3/20 = (20-17)/20 = 20/20 - 17/20 = 1 - (1,7)/2 = 1 - 0,85 = 0,15

1/2 = 0,5
