Question

Zapisz Ułamki w postaci dziesiętnych:

a 3 i 1/2 b 7/4 c 9/18 d 27/20 e 3/25 f 1 i 2/5 g 126/200 h 2 i 105/250 i 24/15

Answer 1

Zadanie 1
a)  3  1/2 = 7/2 = 3,5
b) 7/4 = 1,75
c) 9/18 = 0,5
d) 27/20 = 1,35
e) 3/25 = 0,12
f) 1  2/5 = 7/5 = 1,4
g) 126/200 = 0,63
h) 2  105/250 = 605/250 = 2,42
i) 24/15 = 1,6

Zadanie 2
0,8 = 8/10 = 4/5
0,75 = 75/100 = 3/4
3,25 = 325/100 = 13/4 = 3  1/4
0,3 = 3/10
1,2 = 12/10 = 6/5 = 1  1/5
5,08 = 508/100 = 127/25 = 5  2/25 
2,125 = 2125/1000 = 17/8 = 2  1/8
21,5 = 215/10 = 43/2 = 21  1/2
17,008 = 17008/1000 = 2126/125 = 17  1/125
