Question

va rog eu mult!!!!!​

Answer 1

6/8 si 3/4

6x4 = 3x8

24 = 24 (a)

36/18 si 10/5

simplificam cu 2 ambele fractii

2 = 2 (a)

45/11 si 135/33

simplificam a doua fractie cu 3

45/11 = 45/11 (a)

1,3/5 si 3,9/15

simplificam a doua fractie cu 3

1,3/5 = 1,3/5 (a)

(2³·2²)/3 si 96/9

2⁵/3 = 32/3

simplificam a doua fractie cu 3

32/3 = 32/3 (a)

0,25/4 si 4/64

0,25x64 = 4x4

1/4x64 = 16

16 = 16 (a)

(2 + 1/2ₓ4/3)/40 si (5/2 - 2/3)ₓ0,(18)/5

(2 + 1/2ₓ4/3)/40 = (2 + 4/6)/40 = (12+4)/6]/40 = (16/6)/40 = 1/15

(5/2 - 2/3)ₓ0,(18)/5 = (15-4)/6]ₓ2/11 = 11/6ₓ2/11 = 2/6 = 1/3

relatia este falsa
