Answer 1

Răspuns:

Explicație pas cu pas:

a) x= (9 ori 0,(2)) :4

X= (9 ori 2/9):4

X= 2/4 se simplifica cu 2

X=1/2=> x=0,5

b) x= (2 intregi si 1/2 ori 1 intreg si 3/4):4

X= (5/2 ori 7/4):4

X= 35/8:4

X= 35/8 ori 1/4

X= 35/ 32=> x= 1 intreg si 3/32

C) x=(3,5 ori 0,25): 1,4

X= 0,875: 1,4

X=0,625

d) x= (3/8 ori 1 intreg si 2/3): 2/5

X= (3/8 ori 5/3) : 2/5

X= 5/8 : 2/5

X= 5/8 ori 5/2

X= 25/ 16=> x= 1 intreg si 9/16

e) x= (2^4 ori 2/7) : ( 1+ 2^2+2^3)

X= (16 ori 2/7) : (1+4+8)

X= 32/7 : 13

X= 32/7 ori 1/13

X= 32/ 91

f) x= (1,5 ori 2,4): 9

X=3,6:9

X=0,4
