Answer 1

            a₂        6          3  

a)  k = ----- = ------ =  -----   ,           b₂ = k · b₁ = ³/₂ · 3 = ⁹/₂ = 4½

            a₁        4          2                  c₁ · k = c₂

                                                       c₁ · ³/₂ = 3,75

            b₂                                            c₁ = 3,75 : 1,5  =37,5:15 = 2,5

b)  k = ----- = 7½ : 3 = ¹⁵/₂ · ⅓ = ⁵/₂

            b₁                                              a₂ = a₁ · k = 3· ⁵/₂ = ¹⁵/₂ =7½

                                                          c₁ ·k = c₂

                                                         c₁ · ⁵/₂ = 12

           a₂         5                                 c₁ = 12 : ⁵/₂ = 12 · ⅖ = ²⁴/₅ = 4⅘

c)  k = ----- = -----

           a₁         4 

                                         c₂ = c₁ ·k = ⁵/₄ · 2,8 = 3,5

                                          b₁ · k = b₂

                                           b₁ · ⁵/₄ = 4

                                            b₁ = 4·⅘ = ¹⁶/₅ = 3⅕
