1 / 3 = 1 ∙ 4 / 3 ∙ 4 = 4 / 12
1 / 4 = 1 ∙ 3 / 4 ∙ 3 = 3 / 12
She spends:
1 / 3 + 1 / 4 = 4 / 12 + 3 / 12 = 7 / 12
She have left:
1 - 7 / 12 = 12 / 12 - 7 / 12 = 5 / 12
1 / 4 = 1 ∙ 3 / 4 ∙ 3 = 3 / 12
She spends:
1 / 3 + 1 / 4 = 4 / 12 + 3 / 12 = 7 / 12
She have left:
1 - 7 / 12 = 12 / 12 - 7 / 12 = 5 / 12
