Answer 1

Răspuns: ↓

Explicație pas cu pas:

1. Care dintre ele sunt proporții?

a. 12/13 = 6/26 <=>

<=> 12 • 26 = 13 • 6 <=>

<=> 312 = 78 <=>

<=> 312 ≠ 78 [ F ]

b. 6/12 = 13/26 <=>

<=> 6 • 26 = 12 • 13 <=>

<=> 156 = 156 <=>

<=> 156 = 156 [ A ]

c. 6/13 = 12/26 <=>

<=> 6 • 26 = 13 • 12 <=>

<=> 156 = 156 <=>

<=> 156 = 156 [ A ]

d. 12/6 = 26/13 <=>

<=> 12 • 13 = 6 • 26 <=>

<=> 156 = 156 <=>

<=> 156 = 156 [ A ]

e. 26/6 = 12/13 <=>

<=> 26 • 13 = 6 • 12 <=>

<=> 338 = 72 <=>

<=> 338 ≠ 72 [ F ]

Succes! :)
