va rog repede dau corona​

Answer 1

Răspuns:

Explicație pas cu pas:

a) 1/4, 3/4,  1

1 întreg = 4/4

1 - 3/4 = 4/4 - 3/4 = 1/4

1 - 1/4 = 4/4 - 1/4 = 3/4

__________________________

b)   3/4,  1/2,  1/4

3/4 - ²⁾(1/2) = 3/4 - 2/4 = 1/4

3/4 - 1/4 = 2/4 = 1/2

________________________

c)  1/2,  1/6, 2/3

²⁾(2/3) - ³⁾(1/2) = 4/6 - 3/6 = 1/6

²⁾(2/3) - 1/6 = 4/6 - 1/6 = 3/6 = 1/2

___________________________

d)  

7/12,  1/6,   5/12

7/12 - 5/12 = 2/12 = 1/6

sau:

7/12 - ²⁾(1/6) = 7/12 - 2/12 = 5/12
