Buna! Va rogg ajutati-ma rapiddd ex acesta Dau coroana ​

Answer 1

0,(6)=6/9=2/3=16/24

0,8(3)=75/90=5/6=20/24

0,375=375/1000=3/8=9/24

(16/24+20/24+9/24)÷3

(45/24)÷3

(15/8)÷3

(15/8)×(1/3)

15/24

5/8

Answer 2

Răspuns:

c) Ana

Explicație pas cu pas:

$0,(6) = \frac{6^{(3} }{9} = \frac{2}{3}$

$0,8(3) = \frac{83 - 8}{90} = \frac{75^{(15} }{90} = \frac{5}{6}$

$0,375 = \frac{375^{(125} }{1000} = \frac{3}{8}$

$m_{a} = \frac{0,(6) + 0,8(3) + 0,375}{3} = \frac{ \frac{ ^{8)} 2}{3} + \frac{^{4)} 5}{6} + \frac{^{3)} 3}{8} }{3} \\ = \frac{ \frac{16 + 20 + 9}{24} }{3} = \frac{45 ^{(9} }{3 \cdot 24} = \bf \frac{5}{8}$
