Answer 1

$\frac{4}{6} = \frac{2*2}{2*3}=\frac{2}{3} \\\frac{6}{8} = \frac{2*3}{2*4}=\frac{3}{4} \\\frac{6}{10} = \frac{2*3}{2*5}=\frac{3}{5} \\ \frac{8}{12} = \frac{2*4}{2*6}=\frac{4}{6}=\frac{2*2}{2*3}=\frac{2}{3} \\\\\frac{10}{14}=\frac{2*5}{2*7}=\frac{5}{7}$

$\frac{12}{20}=\frac{2*6}{2*10} =\frac{6}{10}=\frac{2*3}{2*5}=\frac{3}{5}\\\frac{20}{30}=\frac{2*10}{2*15}=\frac{10}{15}\\\frac{28}{40}=\frac{2*14}{2*20}=\frac{14}{20}=\frac{2*7}{2*10}=\frac{7}{10}\\\frac{50}{100}=\frac{25*2}{2*50}=\frac{25}{50}\\\frac{420}{630}=\frac{2*210}{2*315}=\frac{210}{315}$

Salut!

Răspuns:

Explicație pas cu pas:

(4/6)⁽² = (4:2)/(6:2) = 2/3 (2 supra 3),  unde / = linie de fracție

(6/8)⁽² = (6:2)/(8:2) = 3/4

(6/10)⁽² = (6:2)/(10:2) = 3/5

(8/12)⁽² = (8:2)/(12:2) = 4/6

(10/14)⁽² = (10:2)/(14:2) = 5/7

(12/20)⁽² = (12:2)/(20:2) = 6/10

(20/30)⁽² = (20:2)/(30:2) = 10/15

(28/40)⁽² = (28:2)/(40:2) = 14/20

(50/100)⁽² = (50:2)/(100:2) = 25/50

(420/630)⁽² = (420:2)/(630:2) = 210/315
