Explicație pas cu pas:
3/5 = 6/10 = 9/15 -> fractii egale
²⁾(3/5) =(2x3)/(2x5) = 6/10
-> am amplificat fractia initiala (3/5) cu 2, respectiv cu 3:
³⁾(3/5) = (3x3)/(3x5) = 9/15
_______________________________________________
1/4 = 2/8 = 3/12
-> amplific fractia initiala cu 2, respectiv cu 3:
²⁾(1/4) = (2x1)/(2x4) = 2/8
³⁾(1/4) = (3x1)/(3x4) = 3/12
___________________________________
5/4 = 10/8 = 15/12
-> amplific fractia initiala 5/4 cu 2, respectiv cu 3
²⁾(5/4) = (2x5)/(2x4) = 10/8
³⁾(5/4) = (3x5)/(3x4) = 15/12
