To isolate the variable in 1/4x multiply by _ or divide by _

 To isolate the variable in ¹/₄ x multiply by 4 or divide by 1

Step-by-step explanation:

              Let                  ¹/₄ x = a

multiply by 4:          4 (¹/₄) x  = 4 a

                                      1  x  = 4 a

divide by 1:                    ¹/₁ x  = ⁴/₁ a

                                          x  = 4a    [x is now isolated]
