Question

          Stabiliti valoarea de adevar a propozitiilor:
a)$3,8=3 \frac{4}{8} <strong>; </strong> b)2,02=\frac{101}{50}<strong> ; </strong> c)0,0035= \frac{7}{2000}$ .

Answer 1

a)  38/10=19/5
3.4/8=28/8=14/4
ca sa faci comparatie trebuie sa ai acelasi numitor
19x4/20 si 14x5/20
76/20  ≠ 70/20 (F)
b) 202/100=101/50
si 101/50 deci sunt egale⇒(A)
c) 35/10000  si 7/2000(A)
7/2000=7/2000
